You will find prices vary as do the quality of the home's furnishings, amenities, electronics, etc., from home to home. Some have better TVs, free internet, free phone calls, high end mattresses, etc (but all of this doesn't come cheap of course, to the homeowner that is).
It really depends on what you're looking for, first of all, what size home do you need? Start with # of bedrooms.
Do you want your own private pool?
Do you want amenities like free internet?
The resort is all gorgeous and brand new, it would be almost impossible to find anything bad in the resort, so there's nothing I would put on my "avoid" list necessarily (although my DW, who is very picky about where we stay, wouldn't agree with me at all in this regard, she cares a lot about decorating, bedding, etc).
If you go and check the "reviews" sub-forum there are many reviews of DISsers who's stayed in various homes in Windsor Hills, I'm pretty sure most are positive too! It's not going to help you though if you're looking at a condo and people respond to this post who've stayed in larger pool homes, for instance, so for starters, pick the size / type home you're interested in and go from there!
