I also got the crate size 18x12x14 and the crate cover set from Amazon.
These were great deals, and the crate came with a divider.
I have an Amazon Prime membership, so I got free 2-day shipping, which cost me $21 for the crate.

I don't confine him in a crate all day long, so I got a free-standing gate from eBay.
(You could easily get a gate at a cheaper rate, but I wanted a sturdy, free-standing one so that I can move around and place it anywhere I need without installation.)
