I can chime in on this a little. I picked up a 2000 315 R a few months ago for the same price range. I chose the 315R because it seems to be well liked and is built pretty solid, plus I could get one in the price range I was looking for. I haven't done much but clean the carb and make minor adjustments here and there. Just slapped a new set of Dunlops on it today. I really like the bike and think it was a solid purchase for a first trials bike. I rode my first event a couple weeks ago and had a blast with it. Now I have a bug and want a vintage one too so I can ride both vintage and modern! I really like trials because I can have fun and not completely wreck my body or kill myself. I also like how it is a competitive sport, but doesn't seem to have the string of douchenozzles that other types of motorsports have. I tried to get back into dirt a few years ago and snagged a KTM 520. Went right back to "teenager stupid" and figured I needed to try something a little more fitting before I tore something up really good. Shit just doesn't heal like it used to. I suppose it doesn't help that I am fat and out of shape though. I think you would be really happy with it if it isn't a complete pile of sheeite.
