Looking for a tank/combo system

[1986CJ7]

I'd be willing to travel if the price is right, I just want a small/medium tank to setup for the kids.

Nothing more than 400gal ...

Just kidding on that one, I wish, wifey would probably skin me alive this. Nothing fancier than an RSM, preferably wild old, but "working" condition equipment. Again, price is a factor, but I'd come and pick it up, I do have some of the parts already, and instead of building a double Biocube 29 I'm thinking I should be looking into an RSM or equivalent.

Let me know what you have peeps. Please no junk, if I end up spending some cash I want to have this for the kids until I'm ready to set up the new, big one.
