Alright this is what I have:
Conquest Reg (Just reg)
68 Co2, hydroed 5/02.
45/45 Dynaflow dated 3/01
Conquest has some marks on it from removing pieces to rebuild it. Comes with a complete rebuild kit, only part used is the reg seat, which has not been used yet. Old one is still usable, and is in the kit currently.
68 Co2 is immaculate. Little - no marks. It may be anti-syphon, but I'm not sure.
Dynaflow - Tank is immaculate, the reg has a couple of marks, nothing major. Also comes with a complete, unopened rebuild kit.
Conquest- 150 shipped
68 Co2 - 100 shipped
Dynaflow - 200 shipped SOLD FOR 230
All are relatively negotiable. I'm willing to trade, but only for new style Max-Flows.
