I'll let you know how much of a success it is when I try and draw something!
Dervish: I never really tried paintball, and got straight into airsoft. I think it was the camouflage and more realistic-looking guns that did it for me, as well the milsim aspect. Paintball here in the UK is often more of the 'speedball', consumer-friendly kind of game, as opposed to more intensive and more niche airsoft.
The equipment is expensive, you're right - though most good sites will have rental equipment you can use if you just want a taste. Shame there's not somewhere near you though!
