First boat for surfing under 21 feet, and $25k-30k

I have been watching the fun everyone has surfing at the lake this summer and would like to join in the fun. (i would also like to be able to do some wake boarding and tubing as well)

Our lake has a strict length restriction of 21 feet excluding a platform. (They actually use a tape measure to check)

I would also like to keep the price under $30k - i could go up a little higher in a pinch

I have been reading the forums and have seen a lot of recommendations for older boats that are slightly longer than 21 feet.

I have been looking at Nautique 210's, Wakesetter VLX and XTI's, Maristar 210's and 225's, a Tige 20V, several xstars and probably several others that i am forgetting

Any thoughts?

thanks !
