Dimensions??(just footprint) as that deems how many people that stand would be applicable for.
Right off hand I'd say if you like cherry stain and it comes with the canopy alot. It looks of quality so I wanna say at least around 500.00 for both or so. But that's alot of wood and larger stands just generic will run you alot of $$. Just make an offer and say if it's not suitable you can negotiate.
That stand looks to be built of a fairly good grain of wood, and the wood was definitely well picked out. I'd ball park a new price on that around 700-1000, used, you might shoot for $400 to low ball and negotiate from there.
It's hard to get any real construction detail from your pictures BUT it looks to be well built and quite attractive. I wouldnt think an offer in the 450.00 to 550.00 range would be out of line for new. It's a judgment call (depending on why they are concidering selling it to you ect...) what to offer for a used one. Although very nice... stands of that size have a nery limited market.
