not quite sure what you looking for but I have bought a stand from Ikea for my HS10. It's basically a tower hi-fi stand, aroung 100cm tall but does do the job admiraby. I'll have a look for the name of said item later and try and post a screen shot.
Basically whether I buy the Z1 or the HS10 it'll have to go in front of the sofa. Because our picture will be fairly high (above a dado rail) the projector will need to be reasonably high too. The only dedicated projector stands I've seen are basically for OHPs and therefore look fine in a classroom/meeting room but a bit 'clunky' in a lounge. Sony did a slim, chrome, single pillare jobbie for the HS1 that would look fine in the lounge.
I'll have a look through the Ikea catalogue, but it'd be great if you could post a screen shot of your arrangement too.
