Oh wow you've got a couple of classic hardware I like. I'm surprise you don't have a DX-7!
I have a Yamaha XS8 and Access Virus TI. Former hardware was a Motif ES6 and a Roland SH-201. The Virus can't quite emulate the TB-303 compared to the SH-201, but it can still make acid sounds
Even with this new hardware I've not had time to work on any songs, so I spend more time tinkering with sounds and emulating old school sounds. It's quite enjoyable. The Virus makes some serious wicked sounds with little effort.
As for the Amazon deal... there's not much I can do besides ask them to take it down. It's just not fair for people out there. [shrugs]
Do you still use the TB-303?
