The second one is too small and in my opinion the first one is too small as well. I think that they should be at least 4 feet wide by 2 feet deep.

It’s interesting that this person is selling these on ebay – have you tried costing out the supplies on your own? But these do actually look very nice and basically they give you every premade it sounds like but you have to make the grids yourself.

I made a two story condo using NIC panels and other materials for my 2 Flemish measuring 98in long x 42in wide x 56in high. All said it cost me roughly $300 but I also bought some tools and such so it was a bit cheaper then that. Now the building the cage took 2 days but I was a first timer. The buns love it, and I doubt you’d need as big so it’s an option for you.

Those are extremely over priced for a “kit.”
If they were actually assembled it would be OK to pay 2-3 times the material cost, b/c you were paying for someones time and labor.
As it is though, all you are saving time on is buying the supplies.
Those look to be around $40-$80 worth of supplies and you still have to “assemble” it.

Check out anyone of the many tutorials not only on this forum and website, but all over the internet, and make one that fits your needs perfectly.

Looking at those, I wonder… If people will pay that for a “kit” I wonder what they’d pay me to come to their homes and custom design one that fit their space and make one?
I’m unemployed and could use the money.

3 grids X 2 grids is the smallest you want to go for a single rabbit. It comes out to about 8.1 sq ft (bottom level).

Off the top of my head I know that you can get a pack of 23 grids at Kmart for $19.99. You’d need two packs so that’s $40. You can get plywood, cut for free, at a hardware store for $10-15. Flooring for around $10-15. Zip ties for about $6. You could build something a lot better for a lot less, I think.
