I got one when it was at 1saleaday ($15+$5 shipping). I don't actually have a Galaxy Tab, but after using this with my Nexus 7 for a week, I'm considering getting one just because of how awesome this kb is. The only thing it's missing is a backlight. I highly recommend it at this price if you need a BT KB for an Android device.
If someone could confirm that it fits the 3G tab and not just wifi, I would appreciate it.
