Here in the UK, the silicone bands seem well stocked but the Leather and Metals are quite rare.
I managed to snag a metal bad from Amazon, which arrived yesterday; and while is absolutely not worth it's price... it is pretty damn nice to see and feel :)
I have a leather one on order too which amazon is saying Arriving 10 May - 22 May.
Joy!
Non-garmin quick-fit bands now available at reasonable price.

These look amazing and so inexpensive! Looking forward to hearing your reviews so I will know if the quality is enough to warrant buying one of every color!!!
