Sniggler,
I bought an almost new 12 foot wood boat this fall. The price was right so I didn't put too much thought into my purchase. However, after doing some research and making a few floats I would make a few changes.

1.) I'd buy something in the 14 to 17 foot range (enough to fish 3 people + gear).
2.) I'd get fiberglass or aluminum since they're less maintenance than wood. I'd be happy with either.
3.) Having the option to add a motor would be nice...its hard work getting back upstream in those situations where you'd like to run a drift more than once plus a motor could be useful for fishing lakes.
4.) Locking storage would be a nice option as I often fish alone and have to tote rods and tackle with me when making it back to the truck.

I agree with you on buying used. With a drift boat its not like you have to wonder about the condition of the engine. All you have to do is look at the boat and you can pretty much tell its condition.
