Think about the cylinder options
I'm not going into my usual detail, just search through my posts as I've repeated it plenty of times
£150 for a fibre cylinder
£40 for an aluminium cylinder
Most fills available are 3000psi, most guns can survive most games without running out of air
If you are flush with cash then go fibre, if you are small then go fibre but with one of the compact cylinders so it ergonomicaly fits
Otherwise go for spending only about £40 and keep the change for paint and gear
