price wise, lets see:
3 & 5 - tools... depends a lot on what marker you use, i just take the allen keys i need and a special wrench for my impulse, and a phillips screwdriver... so mine probably cost me £15ish
4 - orings... cheap for CO2 ones... seals for inside of marker more expensive... All my impy spares probably cost me about £30.
7 - gun oil.... depends on what u use... Dow 33 for my impy about £10 but lasts forever and longer
8- paintball cooler... what the hell is that, no need in the UK!
9- goggle lenses etc... lenses about £15 but obviously depends on what goggle sysytem u use
10 Goggle fan - don't use one, never needed it but the vortex is like £40ish from Planet.
11. Batteries and hopper... 9vs vary, decent ones like £4ish each... i need 3 spares so say £15... spare hopper (12v revvy) about £50.
12 Spray Bottle... DIY stor job.. £3/4
13. Barrel bags etc... came with my goggles and barrel.. otherwise barrel bags are like £10ish
14. Extra pods.. we have team pods but they're likt £2.50 each.. say £15 for spares
15. Squeegies... i have a straight shot (£10ish) and a barrel polisher (£8ish) say £20 total?
17. Podgee.... never heard of
18 Talking timer... cool idea but no idea of cost guess £5
20. JT Gearsack... mine is sooooo sexy
but expensive at about £120.
Total roughly... £180/ £220 with a goggle fan but that's if u have nothing at all hanging around at home and u buy it all new..... plus a gearsack if u wanna shell out for it.
