Wilson Combat is selling a phosphate BCG with an MPI bolt for $98.00 right now. Personally, I prefer the phosphate finish because it is designed to hold lubricant on the surface. It's not fancy, but it serves a purpose.

So, I would suggest checking out Aero Precision, Wilson Combat, or BCM. But for $98, you're not going to find a better deal than Wilson Combat.
What's Aero's forging stamp?
