cheapest bins?

what is the cheapest bin that you can use in a rat rack and where can ya get them?

i really dont like the idea of spending $8 per large litter pan when i want to build a 6 tub rack...

what size is best for rats?

I use large bus tubs from a hotel and restaurant supply store. they run me like 5.45 each you might look at getting some of those

I bought concrete tubs, like 6$ each, pretty big too

The Concrete Mixing tubs work really good. I thought they where only $3-4 at Home Depot. i could be wrong. I have had them in use for about a year with no problems.

Those are the one I use http://www.amazon.com/Doskocil-Litte...6395190&sr=1-2 (Shipping is $5 regardless of the order size)
