You can find used nanocubes for around 175-250 with stand. I got mine at the lower end of that range, but had to buy bulbs and fans for it, about 70 bucks. I did get liove sand and about 15lbs of live rock which helped, but still had to put more into it. I think the 24gal DX with PCs is around 300-325 shipped with a nice stand brand new.
