Highly recommended. It's a great camera, I love mine. (Obviously, I'm not selling it.)
There are images on my website (see signature) that are taken with the RF645, but it will take some browsing to find them. (Just on the most recent shot I added RF645 as a tag; I should edit other posts and include camera tags as well. Usually I do include it in the description, at least per "set" of photos.)
I've bought mine from eBay (body + 65mm), later added a 45mm and the flash, both from ffordes. I see they don't have any for sale right now, but it is a possible source if you want one.
