if your a beginer try out a basic gun first like a tippmann cronus unless of course you have played paintball enough times to decide you want to make it your hobbie.
Completely disagree.
Quality, second hand paintball gear holds its value pretty damn well, and a lot better than cheap new stuff.
If you bought something like a second hand Empire Axe as your first marker, played for a few months and then decided you didn't want to keep playing you would be able to sell it for the exact same price you bought it for, provided you hadn't done any damage to it.
Something like the Cronus though, you'd likely be looking at losing half of its value within a few months, and that's if you could even sell it, because there is virtually no second hand market for really those kind of really cheap markers.
Much better off putting your money into quality gear right away, you'll be better off if you decide to sell up, and it'll last you much, much longer if you decide to keep playing.
