Syntecno Teebee

I've owned a mkIII for a while now. I love it, it's my baby etc. However lately I'm starting to find the sokkos os for the x0xb0x really appealing. Due to Teebee's being kinda rare I've no idea what to ask if I were to sell it. I think I saw another mkIII on Ebay a while ago but don't recall what it went for.

info or opinions are appreciated

edit

eh, disregard my asking (probably just end up keeping it). It's probably worth more to me than the buyer. Sentimental reasons, I guess.
