I can't speak highly enough about KEH. I just looked at my account, and in the last year I've bought 45 items (11 order) online, and another ~20 items/3 orders over the phone. So about 65+/- items.
I have bought every grade they have, including UG and AS-IS. Of all those 65 items, I've had to send back one item, as it had very oily blades. They serviced it, and I had it back within 7 days.
The reps (Greco, Arthur, and others) are always a pleasure to work with.
Hmm.... the old vs new website. Yeah, I liked the old one better, but honestly, I've gotten used to the new one. Still like the old one better, but hey, I still find what I want/need, and that's all that matters. If you aren't keen on the site, it's no problem to call them and ask if they have something.
Just adding my 2 cents.
