$1500 seems like a nice number for a nice, high-quality/name build. I've priced sub-$1000 builds using quality barrel/parts, but not using railed forends or fancy carbine stocks. KISS is good.
To be perfectly honest, an OBR would be wasted on me. I'm not a terrible shot, but I'm not up there yet. My Mini 14 does decently enough, 3-4.5" @ 100yds if I do my part.
