looking for used jon boat to buy

Hi, im looking for a used jon boat in the area for about 200$-250 at most, its my first boat and im on a budget but if anyone wants to part with theirs let me know! thanks!

Ill probably just start out with some oars, I just wanna get out on greenlick, cranberry, etc

Pretty much what Blue said.  I have been eyeballing jon boats for about 2 years.  You're likely not going to find much under $200 and give yourself budget for accessories.  $200-$250 is on the low end for 10'-12' without trailer or anything else thrown in.  Most are looking for $300+.  If you are looking trailer, boat and reliable (gas) motor, finding all for under $500 is going to be a challenge, but there are deals out there.  Electric trolling motors seem to be a pretty inexpensive item though, I've seen from $50-$150 pretty regularly.  You will need a new battery, costing you $75 or so though, and a charger if you don't have.  Then plan on adding an anchor, depth finder, rod holders, ect.  Keep track of the accessories that many offer, compared to having to buy seperately.
 
Craigslist is the way to go if you are in the Pgh area.  Pennswoods seems to have much better deals, if you are outside of town.  But they cover a lot of real estate.  A great deal + $60 in gas & 1/2 day driving to pick it up 150 miles away and back, might not be such a great deal when said and done.
 
Make sure that you are able to register it.  I'd get it notorized when you buy, which you pretty much need to do if it has a trailer.
 
Good luck & welcome to the board and level 2 of your fishing addiction...
