I think that's what I'm gonna do. Just waiting on the other party. Evidently this is a 3 way split. Instead of me trading for the Impress, hes trading the Impress for a Versus City, which makes his Astro available for my Blast, and his friend wants to trade the blast for something else.
All I know is if the deal falls through I don't have any kind of loss. They said they are working on transport, and all that. So who knows, maybe it'll work out.
edit: re: Atomiswave/Naomi - I've got the MGCD which is my knockoff Naomi/Atomiswave lol so even a 15khz will work just fine. I'll never have the extra cash to drop on a complete Naomi set up with a multi/netboot/whatever its called. Maybe an Atomiswave, but the last AW I had before was in a standard rez dynamo cab several years ago. So even if I were to get an AW, it would still work fine in the Astro.
We'll see what develops.
