I just bought one from PY, very long story and still not sure why I bought from them. Nonetheless it has had major condensation issues since day one, you have to tap on it to get it to work and it is VERY dim (and yes, I have a good ground and an excellent power source). I'm guessing Ames sells the same brand, however, I'd feel a lot better about Ames taking care of this for me than I do PY...
