I wouldn't think so. And even if they did, the suits would be outrageously overpriced. Being the Star Wars nerd that I am, I've seen quite a few of these and I've their prices waaay up there. You could try eBay, though. I hope this helps.
I am a member of the 501st Legion (I'm a stormtrooper). Most of us make our own armor. The link provided by Ursula is an excellent resource. Once in awhile you will be able to find armor on ebay. If you are *seriously* interested in joinnig the 501st, you can go to our webpage: www.501st.com where you will be able to contact someone who can help you locate armor. PM me if you have any questions about the 501st.
