If you don't want an exact copy, the Reverend Daredevil HB is a great choice, it's definitely in the vain of the SG. Great stock pickups and they can be had for about $500.00.
What is keeping you from buying an SG? Are you looking for a lower price range? It's hard to answer your question without knowing this.
PRS Mira gets my vote
here ya go..shipping will be kinda high but its worth it, if these are anything like the les paul i had

If you ever see a Guild S-100 Polara, grab it. It's their take on an SG, not a copy, and it's not produced any more since Fender bought Guild.
I had a late-90s version (from the old Westerly RI plant) that I paid $750 for with HSC. An excellent guitar, wish I hadn't traded it. ==K
