Where can I buy an Aeotec Gen5+ US Version?

1

I’d really like to get a 500 series Z-wave stick that supports SmartStart. I’ve not had good luck with Zooz sticks so I was hoping to find an Aeotec Gen5+ (has to be the +). Anyone know where I can buy one? I know they’re discontinued and thus they’re out of stock everywhere.

Or any suggestions for a different 500 series z-wave stick that supports S2 and SmartStart that is in stock? (US version)
