I'm with Kurt on this one. I have two of the 12"x12"x18" ZooMeds, one of which is exactly for my red eyes, and the other for my dumpies. They love them and have plenty of room to climb and move around. Red Eyes don't get all that large, so I'd say it's the perfect size for one. You could even fit two in there comfortably. Just remember to well furnish your terrarium with PLENTY of things to climb on.

Good choice, and nice price on that. I got mine for a bit more. Nice find.

Looking forward to seeing updated photos of whichever you so choose to go with.
