A quaker right? You gotta know about the noise level. They can be extremely noisy. Also did you ask how tame he was and if he is able to be handled? Also why are they giving him away? That is a good price for all that stuff.
I would get him a different cage if you do get him though. That one isn't too bad, but wider cages (instead of ones that are just really tall) are really better because they have more room (plus more room for lots of fun toys.
I would advise against it.
Quakers are banned in Kansas, so you would not be able to provide him with vet care.
Quakers are messy (don't get me wrong, I love them and I miss mine dearly), they like to soak their food and sling it everywhere, plus the food soaking makes them prime targets for yeast infection in the crop, which is what ultimately killed my 13 year old quaker.
