You might also consider a shock fork- that's what I use. There aren't as many out there as there was a few years ago in 1 inch, but they are usually cheap bikes on craigslist- I got one new one on e-bay years back for about $60. Stay away from cheap AMF though. I thought I'd found a bike with a useable shock fork in the trash- an AMF mountain bike, but when I got it off I decided it wasn;t something I'd risk my neck on.
