Personally I'm not much into SGs, too. They feel like lightweight LPs to me. But Tony Iommi is cool - especially his cross inlays. His signature humbuckers are a little overpriced, though.
May I suggest you to keep the Rick, sell the Epi Dot and save for a "worn cherry" or "worn brown" SG special? These are good basic guitars with good pickups and have never been cheaper. Only drawback is the rough finish, but I think that feature's quite charming.
Just my 0.02$, as always. No offence intended. Peace and Love

Although its safe to say in this economy I doubt anyone (even Guitar Center) will want to buy/trade like I'd like, unfortunately :-(
