@UWSkier said, "Other good choices would be a Malibu Response LXi, which has great wakes also but isn't quite as big as the Sunsetter LXi, and the Nautique 206, which is also a real nice boat but isn't as roomy as the Sunsetter."
I agree, and would add the Response LX, which has a step over bow rather than walk-thru. I bought a '98 Lx a couple years ago in great shape for under 12. And I have kids and do some family boating. Kids don't really care about step-over vs. walk thru. More a parent preference. I love my boat. Bu, if I had it to do over, I probably would have saved a little longer and found a 2006+ LX or LXi that was ready for Zero-Off, or had it already installed. (please verify with the As your wife is a former pro, and you "give it" as you say, it is worth it. And at near 25k, you should be able to find a good 'Bu. There are lots out there if you are patient. And 2006+ can be converted to have Zero-Off (without motor replacement at least, 2007 may be easier ), and may have Perfect Pass, hopefully with Stargazer, the GPS piece, and maybe even Z-box, which is the part that tries to mimic Zero-Off. There are other threads on whether you really need/want Zero-Off if you have good working Perfect Pass, and if I were shopping now, I would take the time to check that out. But you should buy a boat that is ready to have it if you want it, without putting a new motor in. Older, and it is a more expensive and bigger project requiring a motor swap.
So yeah, my vote is Response LX or Response LXi new enough for a Zero-Off conversion
PS, you can make a Response make a surf wave with a velcro or suction cup wave shaper thing and some weight, especially, as @Chef23 says, if it has a wedge. Not like a surf boat (thank gawd) but it can be done. And I love, love, love the slalom wake.

EDIT: the Zero-Off FAQ's say 2007 and up works. So to be safe, I would go for 2007. And would accept a few more hours on the boat to do that. Hours don't bother me that much if the boat has been treated well. http://www.zerogps.com/faqs/
