I just got the new Hobbyking Bixler, their newest EasyStar clone, and I'm very impressed. I haven't flown it yet, but based on the design I think it's the best Easystar clone out there yet. (And I've tested them ALL!)
It's available as a kit, a RTF with a 4 channel radio, and an ARF without radio. I recommend the ARF version, which is just $52 (or,if you live in the US, it's available for $58 in the US warehouse with much cheaper and faster shipping). Add a 20a ESC, battery and 7ch radio and APM and you've got a UAV for under $500.
Some of the advantages of the Bixler, compared to the EasyStar and the other clones:
Here are some shots of the Bixler fuselage compared to a standard EasyStar:
