it's best to drive around to different surf shops (i recommend LA or OC beach cities) to look for boards they are clearing out... you may be able to find an untouched stick for around $100. one time i was at my friend's in venice and saw a "sale! clearance!" sign at this hole in the wall in marina del rey and sure enough they had a few quality sticks for between $80-$150. a lot of times in OC you'll be able to find old boards in decent shape left out in the alleys next to dumpsters.
try craigslist too sometimes you may be able to find a deal there. one thing is for sure though if you have been riding fun boards, then try a fish/fishcuit/biscuit as your next ride. something with a wider nose and thicker core. going directly to a ripstick can be discouraging if you've only slid into waves with a log or foam. good luck
