Just poking around their website today I noticed they still are listing the PRS-350 and 650 for sale. They both will add to my cart so it's likely they really do have some stock left. SIG is in Canada but the price isn't much higher in USD.
PRS-350 in silver and pink, $99.99
PRS-650 in red and silver, $219.99
If I didn't already have a 2nd 350 as my spare, I'd get another, that's a great price.
