The visions are the most cost effective from what we were able to find. As far as building your own, well we already had the "joy" of that experience...We figured the extra cash was worth it.
The one from AP I don't think holds nearly as many. This one holds 22..and they accidentally sent us 23 tubs. lol. No charge for the extra...woohoo.
But as for the escapees...our other rack has had three males and two females escape from it. This one we pushed the tubs too far back and the male that escaped before(matt's Christmas present) escaped again.But we found him that day.
The one I speak of is unlisted on the AP site and is an economy plastic that will hold 20-15qt or 10-32qt clearviews.. COngrats on the tubs (nothing like a free tub)
I cant hang with the open ones, i'm way too paranoid about it , lol.
