A lot of peeps here like them, might need a new chain and or sprockets, brake pads etc, but you'd still be in budget. Orange too. Yum Yum. There's a link to Downtube on the right of the page, for more info. Nice looking bikes.
Buying older isn't a problem, if you keep an eye on wear items. My pal is still riding a fifteen year old MTB I sold him five years ago. He's just replaced the chain. :-)
