Advice on converting fork?

Hi folks -

I am considering purchasing a used Fisher Big Sur. It has a Manitou SX fork and since this'll be a utility bike for me (tooling around town, biking to work), I was considering replacing the fork so that it's rigid.

First question: Is this a bad idea? Seems to me non-suspension will be better going up hills, etc. But I'm currently commuting on a mtn. bike w/suspension (crummy, but it's there) so I don't know what it feels like to not have one.

Second question: What kind of fork do you recommend switching to? I don't want to spend a ton of money on the converstion.

Third question: Is this something easy to do, bike maintenance-wise, or is it something more sophisticated, that I should have my LBS handle?

Thanks ya'll.

I'm not a big fan of suspension.

Threaded or threadless? If threadless, all you need is an allen key, and some sort of pipe-shaped thing to hammer the crown race down. You'll also need a hacksaw to cut the steerer. If threaded, you need a headset wrench and a big adjustable.

Make sure your new fork has the same sterrer diameter as the old one. If threaded, it's got to be about the same height too.

If this is a beater, try to find a decent old bike to cannabalize. Most bang for buck.

For road riding, ridgid is a good idea.
Rigid forks come in a variety of styles from massivly stiff, heavy and harsh to light, agile and shock absorbant.
Look for threaded fender eyelets.
You need a compatable steerer, the right length, diameter and style.
Forks come with varing amounts of trail which should roughly match your headtube angle.
Some bike shops have a bunch of used ridgids from old suspension conversion jobs. Otherwise, the Kona Project is a favourite.

Asking questions like this indicates a need for more reasearch and a visit to the www.parrktool.com repair section. It ain't rocket science,but there are plenty of ways to screw up and throw money away.
