Akai VX90, VX600 and Akai EWI 3020m units

Been looking for a VX90 for a little while now, never heard the greatest things about it but it seems fun. I’d buy a VX600 at the right price, one person is trying to sell it well above its value. I’m thinking of trying to poly chain a stack of ewi modules so if anyone sees 3020m units I’d be interested. Thanks!
