All small 250cc's "starter" bikes seem to bottom out around $1k-$1500 range in good running but reasonable used condition. Less if beat or slightly more if well cared for. That bike might list at 4700 ish new but will be worth half that within 2 years. Being the last year tells me that they aren't in high demand or else Suzuki would continue them. Do whatever you want but I think Nick and I hate to see you waste that kind of money. I bet you could buy 2 nice used ones for that price... how's that for reliability?
I have nothing against the bike, its just a pricing thing. Plus if you had a highway commute I would recommend something bigger. My cb250 fights to hold 65-70.
Also, I love my cb250, but I also recognize that a ninja 250 would blow the fictional doors off mine. So if you want slow reliable go cb250, and if you want fast reliable go ninja. Not sure where the tu250 stacks in thag equation but I'm sure its faster than mine.
