Darn, I wish I nabbed this back when it was on sale. Hoping for another sale coming up what with the bad economy and all.

Btw, this model DOES have PFFB (Post Filter Feedback), which is supposed to help sound quality for speakers with difficult to drive loads.

Don't be sad. Aliexpress has it for this price or less!
