I've used them a lot over the past 3 or so years... Don't hesitate to offer the price they're asking on their website when you're checking out their eBay listings. They will accept it 99% of the time. Also, they will ship via USPS Priority Mail, if you request it. Avoids the UPS ground wait-time and possibility of damage to the gear. Sometimes is cheaper for them, other times, it's about the same, since UPS seems to be fairly expensive.
Also, it's best to contact them through their website. They don't respond to their eBay messages, except with the usual canned response. Yet, if you email them via the website, you do get a personal response. Did that when I noticed an error on one of their eBay listings and when I did a top cover swap on my FTn, which voided the 6 month warranty. On the latter, notified them that the camera's serial number had changed and to treat the sale as an as is sale. I probably will do the same with the FT2, since that camera will be going to Northwest Camera Repair once the F has been worked on. Since it's more convenient for me to deal with a local repair shop than to mail equipment back to either them or KEH for servicing, their warranties usually don't apply to me. I don't wind up taking advantage of the extended period. If I lived in Indiana or Georgia, then, yeah, I would.
