I doubt you're going to find many reviews per say. A company kinda "reviews" the product for as long as they're supporting it in the field. It's a learn as you go situation, at least for my company.
If you want me to review your BOM just PM me. I'd be happy to look over it. If you want cheap then I'd go with: QSC, EAW, Soundcraft, Peavey (processor), Behringer (limters only), Ashley (EQs only), Denon/Sony ( playback), Shure (mics).

EDIT: I'd stay away from Mackie and Behringer boards. They're the cheapest out there and they're quite limited in out-of-the-box functionality. If you're limited in funds then you can always crack open a Mackie console and apply some hardware "hacks" to make it work better. Most of these hacks can be found on the internet I believe. You also need to be solid as a rock with your soldering gun.
