Your simple question has a series of answers that could fill a very large book.
This is usually what I tell people-
Buy a name-brand boat. A first boat usually isn't around long. If you like it, you'll want bigger/faster/roomier/racier/whatever in a year or two. If you don't, you'll probably just want it gone. Selling an off-brand boat can be tough- especially when there's no shortage of bargain priced name brand boats you're competing against. Cigarette, Fountain, even Baja- they hold their values better. The boats you list are rare on this end of the country so they may be big, popular brands in the West. But if they held the name recognition of Cigarette and Fountain, we'd see them here. Also, stick to something mainstream. While something unusual might appeal to you, it may not to the average buyer.
Condition is everything- I'd take a high-hour boat in pristine condition vs. a lower-hour one that looks like it's been ridden hard & put away wet.
Service records- There are 3 types of ways to do maintenance. The first is having it profesionally done. The second is the skilled owner that DIY's it. The third is the "whatever- if I remember, I'll change the oil" and also "if it ain't broke I ain't worryin' about it" I'm guy #2 but I have records that detail everything. If a guy doesn't have printed, organized dcoumentation, he's probably boat maintenance guy #3.
All things being equal, newer is probably going to be cheaper in the long run. You may find a stellar deal on an older boat but if you have to scavenger-hunt on parts, that can be expensive.
KNOW what you want before you buy something. Making a boat into something it isn't is exceptionally expensive. Making a 60 MPH boat into an 80 MPH boat can be prohibitively expensive. If you want to go 80, knowing this beforehand and looking at 80 mph boats is going to be alot less expensive.
Survey- unless you're prepared for and not concerned with making a 5-figure mistake, have your final choice surveyed by a well-known high-performance marine surveyor. The guy that does million-dollar yachts all day won't know what to look for, just as the guy who surveys Cigs & Fountains every day would probably be lost on a big sportfisher.
Lastly- on surveyors, they can be more than just the guy who checks the boat out. A good one will share his experiences, his knowledge of the market and also who is and isn't a scrupulous dealer. They may be able to point you in the right direction. I think I'd start by calling around- or asking on here for a referral.
