If you want to stay under $10K think Tristar. Made from '86 (I think) till '90 in a 19' and 22' Both of these include swim platform which is molded so that translates to effectively a 17' and 20' boat. Then the 205 comes out in '91 and that is the boat you want (IMO) to look for. You will find them from $10K to $20K in varying condition and with varying options. IMO, spend a few grand on a better kept boat and it will save you in the long run.
