I picked up a 2nd job (just a few hours a week) and that helps out a ton ($100 a week for 8hrs of "work"). 3 months and you can buy almost any gun setup you want. Security and phone sales are always hiring and willing to work with your time. Ebay is just more time than it is worth (unless you have a lot of junk lying around). Plasma is only good for the occ ammo buy. Bartering is another good way. Do you have a skill? trade it for guns (web site building, basement framing, mechanic, landscaping,etc) A lot of people will trade something they don't use for what they need (aka gun for yard work).
