A few years ago I did the same on EBay and now have 4
Hong Nor Ultra LX2 - Force .25
Hong Nor Ultra LX2 - Force .32
XTM XT2 Terminator 2 - 24.5
Hyper 7 SS - AR.28
All purchased from £50-£85 they all needed a few bits like a glow plug, clutch shoes, rear crank bearing, piston con rod and a tune
(it’s a good hobby if you have patience)
