Before creating your first SBR, what did you consider in a lower receiver?

To me, I'm considering something that is of known quality and reputable. I do not want to submit on something like a Palmetto or Anderson, although I have not ran into issues on either. I also do not want something with a big gawdy logo that may not be so "hot" 10 years from now. I also do not want something that is "fad" right now, ultra chiseled or cutout/hollowed, etc. My consideration is something like a stripped Colt, BCM, Mega, Noveske, etc. These are lowers I wouldnt normally seek just for a range blaster, but now am interested in something like them. I saw an image of a new(?) SLR lower the other day and I really liked it, although it is a little more radical than a standard Colt or BCM for example.

What kind of thoughts/concerns did you consider before purchasing a lower for SBR?
