Yeah, it's best to get one of the more "open" devices if you want support from the community for a long time, and it helps if it's higher end, too, but even if it's low-end it should at least be a popular one.

For example, Galaxy Ace and LG Optimus One were very popular, and they're getting even the latest version of Android for them with CM. And last I checked JB was very fast on them. I also have JB on my own HTC Legend, which was also one of the most locked down phones ever. I went through a lot of trouble, and even had it "bricked" (not final) while trying to unlock it. But now I run a JB CM10 rom on it pretty well.
