Ladies and gentlemen,
Not sure if I am late to this party or not but:
I have recently been doing a great deal of look into picking up some lab style breeding tanks, the detractor of course being the cost. A good lab style cage setup can run you into the hundreds once you get all the snap-ins in place (water bottle or system, food hoppers, etc). In my search I found a site selling cages designed for both mice and for rats or a mouse colony for $19 and $35 respectivly (water bottles not included (food hopper built into lid)). They also sell the water bottles for $5 and $8 depending on the size you want.
Picking a few up on Friday myself http://www.reptilebasics.com/rodent-caging/
