I found the disc brakes to be great when it is wet. Otherwise they are pretty much not worth the added expense, but hey, what do I know. I am too fat and lazy to have even ridden it more than once or twice....
Here is mine. Trek 400 bought used on Craigs List for $200. Excellent bike. I put the tire liners in and haven't had aflat since. Front shocks only. hard tail. I love to hunt this way.
