Just checked out their site & they were pretty cheap.Are they good quality or should I spend the extra bucks & get a set from one of the big guys?

I've bought some stuff from TAPCO over the past few years.  FAL/G3/CETME Mags...ok no problem, gun tools...cheap, worthless Chinese/Pakastani crap, original gun internals....FAL stuff seems ok, but others....crap shoot.    For my recent CAR15 project, I bought the lower parts kit from Georgia Precision.  Their parts kits are RRA.  Bushie/DPMS/RRA parts are the way to go, take your pick. Spend a little extra and have peace of mind.

Thanks,that was kind of the way I was leaning.Just kinda hopeing people were haveing good results with them.I'm trying to build the least expensive AR possible without skimping on quality.
