Is it worth getting? For $30 you get to have guns delivered - at wholesale prices - to your doorstep. You get discounts at Midway and at Brownell's, and probably at a few other places as well. You get to own pieces of history for a song - was that Enfield rifle used to shoot a German general?; did that Mosin M91/30 fight in Stalingrad?; what role did that K-31 play in holding off the Germans from invading Switzerland (along with a few hundred thousand of its friends)?; was this Garand in Patton's Third Army at The Bulge, or did it contribute to victory at Iwo Jima, Okinawa or Inchon, etc., etc. (and, yes, you can see my anti-Axis bias)?
On the downside, you have to record all purchases and sales, make sure that you're not conducting a "business" according to a never well-defined set of rules, and be subject to a possible visit to an ATF office once a year (they're NOT invited to my home, thank you very much). Personally, I record all of my purchases anyway, and I think that the odds of getting audited are very slim if you only buy a few guns a year and don't engage in much selling. I wouldn't be worried about the audit anyway, as the most I plan on ever doing is selling the worst 1 of 2 or 2 of 3 of a particular firearm that I buy - and then only if I don't like them, and not for a profit (after shipping and advertising costs, if any).
Summary-lots of upside, not much downside.
