My Limited Hybrid comes with 235/55R18 wheels, but I'm downsizing to 17" for winter tires. I just ordered these rims, simply because at my store they were the only direct fit aftermarket aluminum 17" rims that would fit the RAV4, and they were relatively inexpensive at CAD$140 (approx US$100). Apparently, they're quite popular for winter tires for both Toyota and Lexus owners.
I didn't want black steel rims, and I didn't want multifit alloy rims either. These end up being about CAD$50 more per rim than the same sized black steel ones, so in total, I'm spending $200 more (or well under US$150 more) to get alloy rims for winter.
