CameraLand is always my first choice and a business I highly recommend. I've posted before about my positive dealings with them and how they've helped folks with issues even when they weren't the sellers, but here's one example from quite a few years ago. Doug had posted a list of some demo optics, including a few that were one-only items, so I got on the phone and ordered. Turns out, someone else placed an order at virtually the same time as I did and got the only model available. But instead of contacting me to tell me the bad news, they called me to tell me they were sending a BRAND NEW scope at the special demo pricing. It just doesn't get much better than that...

EuroOptic is also good to deal with, and I've been very pleased with Optics Trade EU out of Slovenia. They'll often have items you won't easily find here in the states.
