How soon are you looking to buy? I have a 265g I have been looking to get rid of to replace with two 180g tanks.
My setup would include some heaters (I never really used them on the tank, my lights (not included) kept the tank at 78F), a Rosewood color Perfecto Prestige Stand and Canopy, glass tops, all plumbing (the standpipes in the overflows, bulkheads, plumbing for underneath the tank etc, but not the sump).
Tank is only 3 years old, pretty much NO scratches (I don't see any, and I have eggcrate under neath the rocks so there shouldn't be any bottom glass pane scratches either) and the silicone is still clear (not stained blue or anything). You will need at least 1 extra person, preferably two (besides me) to move the tank and you will have to make two trips to get the stand as well in a full size pickup truck.
Tank is 7ft long x 2ft wide x 30"/2.5ft tall, and has overflows.
I wasn't looking to immediately sell it just yet (it has fish in it and I can't sell it this week in other words, but can have it ready in 2-3 weeks at the earliest).
Let me know. The tank itself holds water and is registered with Marineland for their 20year warranty (I sent out the registration card to them after I got it so it should be). I live in Monmouth County, New Jersey at exit 105 off the Garden State Parkway or Exit 13 off of Rt 18. I cannot deliver or meet halfway or anything since I only have a Honda Civic LOL...

Edit: Oh, the light fixtures are two 36" 2x96watt Compact Fluorescent Coralife fixtures with separate power supplies for each bulb, so 384watts total. I've had them sitting directly on the glass tops no problems. They light the tank up very well and are compatible with all CF 96watt bulbs (actinic, 50/50, 10,000K, 6,700K (what I used), etc). I'd want extra for this since it is in relatively great condition (nothing wrong with them really) and cost me over $400 total when I bought them new.
