Old Alexa Studio

Heya, where can I get the old version of the alexa studio and subwoofer? I really really like my studio, and have been meaning to get another + sub for the full surround sound feel.

I guess I assumed it would be able to find it in a physical store somewhere but I'm really disappointed to find they're discontinued like...EVERYWHERE. I'm not too invetested by the new devices, especially since it will take a while for Alexa+ to come to my country anyways, I don't like the new shape as much as the old one, and I strongly doubt any sound improvements would be that important to me.

Follow up question: Does anyone know if my old studio can at least pair with the new ones? If it can, I'd consider biting.
