Vortex Sound Research

As the title says, I’ve been searching marketplace for a while now to find a Sub37 at a good price. I found one and negotiated the price down to $1,250. It looks like it’s in great condition and comes with the original case and everything, just has a little discoloration on the keys. Is this a fair price? For reference, this will be my first professional synth and I’m super excited! Thanks for your feedback.

Edit: Any thoughts on the differences between the Sub37 and the Subsequent 37? The one I'm looking at is a Sub37, but now I'm wondering if it's worth going for the Subsequent model instead.
