Those ROM's are pretty much fully functional, but I guess you can hunt down a bug or two in just about any ROM, on any phone. The only one I've discovered so far (I'm on 2.34.1) is the inability to sync Facebook contacts with the phones contact book.
As you probably know, an official FroYo is on it's way, but there's no telling exactly when it'll be released, sometime during Q2.
I think it's a great phone, a huge bang for the bucks, as it's rugged, water resistant but still really light. And it does it's job, no lag, no freezes, good battery time. I'd recommend it to anyone.
