I've got Look Delta / Arc pedals on all my road bikes
They're available on eBay at very low prices (although I've noticed prices are starting to go up over the last few months), and aftermarket cleats are cheap and easy to get hold of too.
Also if authenticity is a concern, the earlier Look pedals are "right" for a mid 1980s bike.
I prefer the red cleats, plenty of float, and they're reasonably robust.
As to fit, your bike should be fine with modern pedal threads and even if it isn't a decent bike shop will retap the crank arms for not a lot of money.
