Where are you in EU ? I'm French.
I have built a Gen7 1.3 from a Traumflug kit, and my soldering was probably not top notch (was my first electronic kit soldered).
As a result I was never able to complete a full print with that one. The symptom is, it freezes after a random while during the print. Sounds like a bad solder joint to me, but I got lazy and bought a sanguinololu instead.
If you think you have the skill and patience to inspect the soldering job and fix it, I'll send it to you for the cost of shipping only. I'd hate to just throw it away.
Most of my technical comments should be correct, but is THIS one ?
Anyway, as a rule of thumb, always double check what people write.
