It appears to be only one sheet of plywood ($25), some wheels ($15), plastic-coated wire ($25). (I went back and looked again -- the pen is extra -- all you get for $175 is the box with wheels. Would you pay that amount of money for a toy box, because that's about all it is.) Considering somebody spent their time making it, running the ad, etc... I don't have a problem with the price vs. value... (now that I see the run isn't included I do have a problem with price vs. value) I understand you may have no building skills, but I'd say for that same amount of money you could hire local kid to build a better coop.
I'm not sure what this coop is sitting on, but it would have to be on block or something so it doesn't rot out the bottom. I don't see anything that resembles ventilation. There is no treatment for the roof -- shingles, tin. If you live some place hot or some place cold, your birds will not be safe or comfortable. And that "roost" might hold one very small bird, assuming she is able to squeeze in there, but her feet would not lay flat.
You could do worse... but you can do better.
