Hey there's life in this thread yet!
I'm back from the show and it was a lot of fun. Even my wife (who can rarely be bothered to even take digicam snapshots) had a good time. She says she got to watch me in my natural habitat
My haul was a Fuji dark box for $20 plus a load of items from their famous, and mobbed, dollar tables. I didn't know this but we arrived just before they literally took the wraps off the tables, at 10. Good to know for next time. Photos of the scene and my haul below.
The two cameras (Lumix DMC-LZ5 and Oly Infinity Mini) are not quite dead but on life support. For a buck I couldn't resist the gamble. Almost everything else was new old stock. Several filters and shades for my Contax and FSU lenses, a Lloyd daylight loader, a roll of Pan-X 620 (exp. 1974) which will go into my Brownie this weekend, and one of 400NC in 220 (a couple of years out of date) for my Fuji. Oh, and the little black box is a Toshiba light meter that seems to work fine. Reads a little high but that's with the first battery I could find that would physically fit.
I saw and played with a load of neat stuff, and the dealers seemed to be in a good mood. I very nearly bought a Zarya (priced at $50 with a clean I-26) and a Kodak Bantam 4.5 ($20) but resisted.
I would say it's still worth it today (until 4), or even tomorrow (9 to 3). Admission is $5. Not sure about credit card payment. I think you should assume cash. Dealers should be happy to hold an item while you head for an ATM.
