Not sure how good a deal these are as I am not familiar with the maker or quality. That said, it does look nice.

I will add that if you like the triple, it is a knock off of the Saito T3DR. Saito is a well known and respected long time manufacturer and you can buy the real McCoy for less than the knock-off.
