I have a Steinberger stand for my XL-2. It's great. Just like a regular bass stand, except the bottom swivel part is really narrow, and fits perfectly between the tuning knobs and the body.
Got it off the 'bay. I love it. Looked for one for a while, though.
I just looked there, and while I've seen the guy I bought it from selling them doesn't have any of them on right now.
Here's the link, though, for the one I bought. Maybe you could e-mail him to see if he'll have more up for sale soon:
Stand bought off the 'bay
The pictures show it holding g*itars, but my bass fits perfectly. If you want, I could snap a quick photo of my XL-2 on the stand and post it for you.
