Six months ago I bought a new Houston GSP-02 amp at auction ($650)from Simply Music (very nice people to deal with). TMl2 and Trelja make valid points on support and choices but in fairness, the Houston has preformed flawlessly from day one and I see no reason for it to malfunction in the near future (infant mortality issues and such). It is my backup tube amp but I find that I listen to it almost as much as my Art Audio. Go figure! Bottom line is - I feel it's a very nice amp that's easy on the eyes, ears, and wallet.
