Matt -- There should be plenty of v-drives in the 25k/range. It's all personal preference but the v-drives are going to hold their value a lot better than the direct drives -- just more of a market for them. You also get a much better seating arrangement and both more space and more storage. Not sure how hot you are to buy something but there are plenty of good deals out there and in this market, cash is king. People are selling boats for a lot less than asking price just to be able to get out from under the payments.
I'm a Supra fan but if I were in your position I'd be considering whatever brand could offer me the best boat for my buck. All of the top brands will have good boats and almost the same reliability. I think you just need to prioritize what the most important features for your family will be. Stereo? Wakeboard wake? Surf wake? storage? fitting into your garage? local dealer to service it? etc....
