I purchased a Monster Power HTS 3500 last December on Ebay for $164.99. Plus, I received a $50 rebate and it had the full mfg warranty on it. That was the key for me, because if you don't get an authorized product, the equipment protection guarantee and the mfg warranty will not be available. I really wanted the equipment protection, and most of the units being sold on Ebay didn't have it, so I suggest you look carefully to ensure you will get this on whatever you buy. This model has a $100,000 connected equipment proection guarantee, so I doubt I am going to exceed that number any time soon!
Anyway, I can't vouch for all the other conditioners out there, but I really like mine, and it is, I feel, an exceptional deal, it feels very solid, and looks nice. That being said, I personally feel that Monster's cabling is WAY overpriced for what you get. But I wouldn't hesitate to recommend the Monster Power HTS 3500 to anybody looking for a good conditioner for a reasonable price. Good luck!
