I have both the #2 and the Nanostream 6025. I bought both when they first came out. I ended up with the problems of both (one of the #2 shorted out and I have had the support arms of both 6025's break. Having said that, I personally like both, but when you look at cost, the #2 gets the vote their. I have a #2 not using right now if you just want to borrow one to see what it is like before spending the money.
