I bought my first one

from techno.trading.house, and the second one from imobilephonex, who shipped it all the way around the world to my doorstep in just 3 days, which impressed me a lot. They also included a 32GB card and the price was actually *less* than my first one.
I have a silicon case & car charger coming from fantasy.bid, but it hasn't come yet (hence the need for a second Galaxy Note... do NOT drop yours you will cry like I did) so I can't comment on them (except that their shipping is not as fast... lol)
FWIW, here in Canada the HSPA+ "just works" right out of the box; I'm not sure if somehow it picked up Rogers' APN settings from the network/SIM or what but I didn't have to plug the APN details like I've had to when wiping my previous phone (original Galaxy S Vibrant from Bell)
Just can't say enough how much I love this phone - yeah, enough to buy a second while I figure out how to ship the first off to Samsung UK to have the screen replaced! Web browsing and Remote Desktop are finally usable for long-ish periods without wishing I had a computer nearby. No desire to pick up a Nook Color or other tablet anymore, my phone does it all.
Also appreciate that Samsung has added niceties to it's latest Gingerbread build on this phone (at least, that weren't found on my Galaxy S) like the ICS-style mini-icons on folders, and the alphabet quick-buttons down the right side when scrolling through all your apps (kinda like what you see in your contacts list to jump to contacts starting with any given letter) and the MUCH improved calendar app, even with a full-screen widget if you want it on a home screen.
ICS upgrade will be welcome, but honestly I don't pine for it, this phone works SO nicely. Games and movies go without saying, much better on the bigger screen. Just had to mention it
Well that's my experience so far, wouldn't trade it for anything so far!
