I just received my wife's b'day present, an XD-40, last week. Super deal ($399.99 + $25.00 shipping), ultra-quick shipping considering my FFL delayed getting his info to the seller for a day and a half. I got the gun on Monday after having only ordered it the previous Tuesday, so I was very impressed.
I also bought my Kel-Tec SU16 .223 rifle off of GunBroker. Pretty much the same experience, though that purchase was from a private party, not an FFL dealer, so I think the shipping took two or three days longer. But still, I have bought a ton of stuff on eBay, and have probably only gotten about 20% of my shipments as quick as 100% of my GB purchases.
I have not, however, ever sold anything on GB. That will likely change shortly though. I've about decided to sell my S&W 4563 after going to the range yesterday with my wife and her new piece in tow, and she shot groups inside my groups all day long with her XD! I did too for the two mags she *allowed* me to shoot through it! Not positive I'll get an XD, but have pretty much made up my mind that it's time for the Smith to go.
First post here BTW. Great site! Very informative. Take care.
