Sure you can get an 01 FFL, that allows you to buy and sell weapons (except automatics. I think, for that, you need a special NFA license--others would know better than I);however, you cannot get 01 as an indiviual just for fun (like a C&R-- 03 FFL). You must have a busineess establishment (not your basement, unless the IRS recognises it as a business) and the record keeping is much more, and the probability of an BATFE audit is much greater, and the hassel is much more, and unless you plan on buying and selling weapons fairly regularly it is not worth the hassel (to most people). To buy and sell automatics kicks everything up a notch (AFAIK). Easier to just pay to $30 transfer fee (again, unless you are going to be transfering LOTS of guns a year).
For the 03 FFL (C&R) it is $30 bucks for 3 years. You can order the forms from ATF off the web.
