Entry level / value In-wall Surrounds?

[bicclick2002]

I had a couple of questions and needed some advice on some good valued in-wall surround speakers. I am doing this for my parents as they are finishing their basement. Naturally, being an audiophile I never considered in-wall speakers as an option , so I had to do some research (but it's what they want). They're on a fairly tight budget and are willing to spend $150 each for two speakers (approximately $300 total).

I've provided the official manufactures website with the best price next to each:

Polk Audio (TC615i) http://www.polkaudio.com/homeaudio/p...inwall/tc615i/ $79.99 (each)

Paradigm (PV-150) or (PV-160) PV-150, PV-160 $Unknown (little help, couldn't find pricing)

Definitive Technology (UIW 55) http://www.definitivetech.com/loudsp...ng_.html#uiw55 $359.99 (pair)

Infinity (ERS HV250) http://www.infinitysystems.com/home/...USA&Country=US $149.95 (each)

This is just what I have come up with in the short time I have been researching. Any other name brand suggestions, or experiences with any of the above mentioned in-wall speakers (within the given budget) would be greatly appreciated!
