I was planning on meeting with someone later this evening to look at an 11-shelf rack system and incubator (ZooMed Reptibator Digital Egg Incubator). According the the previous owner, he housed his Ball Python collection in the rack and just recently sold of his collection. He states that they were all healthy and there are no issues with either item (they are both functioning correctly). Looking at an AP rack with 12 shelves, I'd be looking at $695 + shipping. He is selling these two items together for under $300. Is the price reasonable for a used rack system (I'm assuming it is), and are there a lot of risks associated with buying a used system? Do you think it is worth it? I'm supposed to meet with him around 5, so any answers you can give me before then would be greatly appreciated.

Also, if I DO get the rack (if you answered "yes, go for it!"), how would I go about cleaning it? I would obviously bleach the tubs, but how would I clean the actual shelf unit and the incubator? Thanks!
