Does anyone know of companies who offer "complete" home theater solutions for DIY'ers like this company:
http://www.4seating.com/Accessories-CompleteTheaterPackages.htm

These kits look awesome for the money but this company has lots of negative reviews. I know it's not totally high-end but I love how the colors and designs are all coordinated. Gives a professional look for a decent price.

Regards,

Those kits are not manufactured by 4seating and you should be able to find other vendors. Personally I can't see buying a total kit if you are somewhat handy. There is a mark up on everything in the package so if you want to make your panels and columns you can save some coin.

wow... those prices pretty much make their products a no-go for me. I'll have to stick to home-made replicas when I do my build. :(

Just a note, I have no personal experience with them, but there have been several negative threads about 4seating.com on AVS.

Who manufactures them? Can't seem to find anything else besides the ones from 4seating.

At one point there was an outfit in Chicago and one based in Florida that sold "kits" similar to this; but, I'm sorry I can't recall their names. You can find sources but it will take some digging.

I tried a quick search and couldn't find the source. I know every year here there is a regional Home Show with a vendor who has a notebook with a full color brochure of a company's products. The show is in February if you want to wait for me to look!
