depends which one mate there are looooads of them about, & it depends what tank- 4500psi's are woth about £95-£110
3000psi are worth from £45-£65
I'll just put the rough price of the marker, though I am NOT telling people how much they can sell their marker for, and no one should low ball anyone on account of what I write- people are allowed to ask what they like, and some markers are upped so they'll be worth more
I am talking about stock markers
the Spitfire mod (improves the eyes tenfold) and the evolve kit (increases efficiency) will increase the value, and condition matter as well, as well as what other kit like barrels & on/off comes with it
LCD: £95
IR3: £100
A4/A4 fly/Joy: £150-£180
05 Speed: £190-£220
G7: £250
Speed 06: £350-£400
G7 Fly: £?
but as people say- they're only worth what people will pay for them; these are the prices that people will pay, but they're worth more in my eyes because of the quality.
btw if I'm wrong tell me & I'll change it no worries
