You won't get stuck with a piece of junk if you have the CL seller meet you at a professional shop to have the bike inspected.Thanks! I am definitely willing to learn. Im just a little bit nervous about possibly getting stuck with a piece of junk 250/300 at my price point. I had a similar incident happen with a craigslist car so im trying to be super careful now lol.
Personally I'd go with a lightly used 250/300. They'll have better resale and are in more demand.
Good luck.
