From my experiences, I like the Monster HTS 1600 when it's on sale. It is reliable, doesn't need resetting and doesn't produce any buzz sound. I have 3 of these because I like them so much.
I would avoid the Monster HTS 1700 at any price. It buzzes, and needs resetting too often. It seems to be cheaply made, compared to the HTS 1600.
I think the Acoustic Research AP-08SC is a great deal when it comes on sale for $20.00. For value, this one is probably top of the list.
Belkin PUR AV have some great conditioners for the money as well.
