Is it just me or does the wording of the post title make you laugh, it's like your after something other than paintball equipment
Anyway you won't go far wrong on the for sale section. Before you buy a mask and if you can i would say try on a few masks because they all fit people different and one that is comfortable on someone else might not be right for you
If your looking for something on a budget that will keep up with top end markers have a look at Empire Mini's or an Planet Eclipse Etek 1/ 2 for between £115- £150 which are both great markers for the cash and you can grab Halo or prophecy 1 for £20-£30 or £40- £50 as for a air bottle you could pick up a cheap stealie but if you've proper got the bug
go with a fibre wraped bottle first time for about between £70- £90 as you will most likely end up upgrading that anyway evan if you stick with the marker and loader for a couple of seasons
Oh and welcome to P8ntballer
