I have a look bike from 1993 and look arc pedals from the same year.
I am looking for an upgrade and want to keep look pedals to go with my look frame.
I have been out of biking for a while and would like someone to recommend what model
Look I should try...

Thank you

For new pedals, Look Keo Easy pedals are a great value, work great, etc. They use the Keo cleats. I highly recommend them.

Look keo 2 max, I have a white pair on my De Rosa and a black pair on my guerciotti, they are great and I would highly recommend them.

+1 on the keo 2max.
the new keo carbon blades are phenomenal but they dont match a vintage bike real well.

Also the all alloy exhustar look pedals are super light and fairly classy looking. I had a set for look delta, not sure if they made them for keo.

Definitely Keo or higher, level-wise. The older "Delta" models are nice, but a lot heavier.

Look Easy is/was the bottom of the line model for modern Look Keo pedals. My experience with Look base model pedals through the years was they usually don't have enough spring tension on their release mechanism to retain your feet on the pedals on the harder efforts like on climbs and sprints. The pedals never released my foot al together, but I certainly felt them lift partially at the back of the pedals which was disconcerting, to say the least.
If you want a pedal that would have the proper operating range to match a competition bike like the Looks, you should get at least a Keo "Classic" or "Max" model, which are/were their mid-model pedals and are really light and have full tension adjustability. I have Look Classics on two of my bikes presently, and I have no problems with them.

Does the Keo pedal use the same cleats as my old Look pedals.
Also, any comments on Time... I know that I asked for Look but I have recently also come across Time pedals

I have some Keo pedals, still in the box. One is slightly scratched but the pedals look like they've never been used or even installed. Email me.

Yes, all the cleats should be common. Stick with the Look pedals, you will have less trouble getting replacement cleats.

I have current Look pedals in red on my C&V D' arienzo/Basso. They match the frame color and enable me to go back and forth with my Look 566 with the same shoes. The red pedals are Keo Classics, hold well, stiff and comfortable.

For a small side benefit, you can get Look cleats with hard rubber "walking" pads already on the cleat. Makes walking of the bike less adventurous.

Yep, the Easys are the most entry level Look Keo. They're also lighter by quite a bit than all but the most expensive Looks because of the lack of spring tension adjustment. They are, by far, the best selling road pedal in our shop, and we feel they're the best value for the customer. Well under a hundred bucks and light, too. As for not having enough spring tension to retain your feet in the pedals, I've never seen evidence of that myself, and I've sold a ton of these.

There's a young guy in our shop who's an absolute beast on his fixie who uses Look Easys and loves them; I'm confident in saying that if they retain his feet in the pedals, they'll retain most everyone else's feet, too.

FWIW, I've got one of the Look Keo Max models on my Pinarello and I've got the Easys on my carbon bike. I can't tell any difference. If I put them on the scale I'd see that the Easys are lighter, and when I paid for them, it hurt a lot more with the Keo Max. YMMV.

Is the rotation the same on both...do they lave lateral and angular rotation. I have a bit arthrtis in my knees

They use the Keo cleats like all the Keo pedals, so you can use any of the Keo cleats you like. Keo cleats are available in 0 degree float, 4.5 degree float, and 9 degree float. If you have knee trouble and find that more float helps, the 9 degree cleats would be a good idea.

The pedals come with the standard 4.5 degree cleats.

No, the old look pedals had what were called "Delta" style cleats. The new "Keo" style cleats are slightly smaller than the Deltas. Delta cleats will not fit into newer Keo pedals. Even the rubber slip-on cleat protectors that you can buy so you can walk on the cleats without damaging them are different because of this.
