Lucky me, I got a Wurlitzer 140 about 25 years ago at a garage sale. I love the thing.I used to own an old Wurlitzer electric piano that I wish I still had.
I'd love to have a Hammond tone wheel organ, but I currently have an 80's vintage Korg 'clonewheel' organ that does a good-enough-for-me emulation of the Hammond sound. I also own a Honher D4 Clavinet, but it's out of commission with electronics problems.
I'd like to own a decent kit of e-drums.
I'm not a big country fan, but I briefly owned a pedal steel guitar and I'd love to own one again. There's a couple of problems though, as one does not just go out and "buy a pedal steel" from a music store. There are no production line made steels, they are all made in small shops or even one-man shops. It's rare to see a used steel for under $2,000, and many of them, especially the double neck models, go for much more. I loved playing mine and regret selling it now, but I had a "baby on the way" and was making room for her.
