Onkyo HT-S5200 vs HT-S6100 vs HT-S7100?

[ak_ka]

Hi Guys,

Need your help. I'm trying to figure out which one of these offers most bang for buck.
Following is the price as of yesterday on Amazon :-
HT-S5200 - $494.00
HT-S6100 - $528.00
HT-S7100 - $585.00

I'm actually looking just for a 5.1, but can't think of any better options than these. The good thing about HT-S7100, besides a few more features, over 6100 is that it comes with speaker stands, which alone cost $140 a pair.

PS: I'd originally planned on Energy Take Classic + a decent receiver, but it seems to be shooting out of my budget, and these options seem to offer a really good value from a trusted brand.

Any help/pointers would be greatly appreciated.

Thanks

AK
