Klipsch is selling refurbished products cheap and I am in the market for a 2.1 system. They are selling both their origonal ProMedia 2.1 and their newer GMX A-2.1 for $99, which would you recomend? The ProMedia's have a THX certification and the sub has 130watts, while the GMX's dont have the THX certification and the sub only has 75watts. But I have heard that the GMX 2.1 is the best 2.1 system out there so I dont know. I'm confused, what should I buy?
