Have to agree with Deborah that it's best to start with more females if you can. Is for the value it doesn't sound too bad. I thing I can comment on having just assembled a new 7 tub (28 quart) rack from XPVC cost me a total of $347.44 for everything including the heat tape and Vision tubs. Last fall I picked up a breeding size male pied for $400 (50% white) so getting one for $200 is a good deal though you didn't say if it was a male or female?
I would see if he has another female of breeding size that he want's to part with instead, especially if you have no plans to breed the pied, to be honest mine is to keep as a pet, it's the one that gets the oohs and aahs when visitors ask to see some snakes. LOL
