You have cash in fist and can't *wait* to buy your armor. Perhaps you're already in the 501st but with a different costume, but more likely this is going to be your first armor purchase ever.
Everything is on EBay with a quick search and it's sooo easy to buy, but before you do consider these questions before buying armor or accessories:
1. Did you locate the garrison in your area and ask for help? Some garrisons can be unresponsive or seem aloof to new members, but others are really good in helping new folks avoid "rookie" mistakes. So get on your local garrison boards and ask the membes what they think before clicking "bid now".
2. Did you check this forum for past topics on this subject? The ad says those rubber gloves are the real deal and screen accurate, but the reality is that in any kind of warm weather sweat will pool in them. Why not check to see what other people are using before buying.
3. Can you buy it cheaper locally? Buying that industrial velcro to complete your suit from the auction site is pretty tempting because you don't have to guess if you're getting the "right" stuff, but in reality it's easily available at any Home Depot. The auction may be a better deal in the end, but it pays to take a short trip to be sure.
4. Is it really "real"? There are a lot of auctions that may say "most accurate", "screen accurate", "made from original molds" or similar, but not all items truly are. This forum was created with the express purpose of having people help you answer these questions.
5. What are the tradeoffs? What the heck is the difference between a resin blaster vs. a PVC, vs. a "hyperfirm" (whatever that is)? Ooh - why not get one of those Master Replicas - since it's LFL licensed shouldn't that be the best? Some items look pretty but break easily, or are very accurate but not very practical to troop with. Chances are the answers to these questions are already on these boards, or can be answered pretty quickly by posting a question.
