I'm currently in the market for a pair of SA GI 1911's, one a Champion (4" BBL), and one a full-size 5", both parkerized.  Do you think I'll be able to find these at the gun show coming up in Chantilly for in the $800-$850 range for the pair, or should I start scouring gunbroker.com?  Sorry for the very specific question, just trying to figure out if I should wait for the show or not.  It's been years since I've been to one of these shows and don't know what kind of prices I can expect.  Thanks.

Both of those pistols are standard guns for gun show dealers to carry and display...not sure of the pricing, but I think that you are in the ballpark.
Did you try calling local shops to inquire about inventory?  Those are guns that VA Arms normally stocks.

If not then DeGoffs firearms in Mechanicsville (Right off I295) had both in a couple weeks ago...
