I owned a Supreme for a few years. I got it from a friend in a trade for my Fly Deluxe and another guitar. I ended up trading it back to him for two guitars that I didn't end up keeping. Stupid decision on my part.
I love Ibanez RGs. I have owned at least a dozen and I currently have an 1987 550 and a 1996 570. The Prestige guitars are definitely nice, but don't sleep on the older ones. They're made in Japan, too and they're great guitars. They're way cheaper, too.
I am the original owner. I just bought it in mid-December. It will ship in the original boxes/packing material. It has never left my desk and it's in flawless condition. I'm just not using it enough to hang onto it.
SOLD shipped UPS Ground. I'll cover all of the shipping and PayPal fees.
You're right. I guess I'm out of the loop on those. There are tons of 22 fret versions on the used market though. I had an S540 back in the early 2000s that was awesome. I don't think the OP would like the super thin Wizard neck though.
Ibanez S Series guitars are 22 fret with a 16" radius (400 mm). The neck thickness is going to vary by model. There's a number of pickup configurations and bridge options. There are tons of used ones out there for very good prices, too.
