I decided to get one to have a try and got the last one for $128. When it was scanned, I was told the price was $198. But the price label was still $128, so I was let go with the "wrong" price and they changed the price label to $198 immediately. If you check their web, now it's $198. I don't know why they increased the price or they initially put a wrong price. I believe the materials would cost more than that price.
To my surprise, it's not bad. Without bypassing the pot etc, it sounds pretty good. I think it may sound better with some mods.
Sometime later, I will open it (with the warrant void) and have a look what's inside there.
