I have dealt with tda trading in NY via ebay and have had reasonable success.
I contacted them regarding some Fuji professional 160 film: 20 boxes for around $40 or something. They said on their posting that it was dated for later this year (I can't remember the exact wording). Once I received the package I realized the film was actually a couple of months out of date. Not REALLY a big deal for the actual film but I didn't like the fact that they actually lied on the listing.
I contacted them about it prior to leaving feedback and their response was an apology and that they would cut me a deal on my next purchase. I felt that was reasonable enough response and I keep an eye on their postings on ebay for any deals.
They were good regarding communication and very prompt with delivery especially considering it was cross border. I would recommend them with the caution of asking a few questions about dates etc. before purchase.
Good luck.
