I also used to have a SG bass (well, EB-O). However, it broke, so I couldn't play for a month until I got my B-15 five string. But you should ask yourself if you have everything you need, like an amp stack, wireless system (don't need it, but still,) enough strings to last you a year, recording software if you have a band, and maybe some pedals if you need them, THEN you should totaly get that bass dude.
I picked up that Schecter Extreme 4 last weekend on sale for $319. I would have gladly paid more. Schecter's seem to be more geared towards metal but it sounds good playing most anything - funk, jazz, metal.
