In my opinion (and it's only mine), the CIPA-type mirrors are not a good solution, primarily because they don't spread wide enough. It is important (and a legal requirement) that the sight lines converge behind the TM. I laid out my thinking here, and I still believe in it.

Having said that, though, several of our members use the CIPA mirrors - they are a bit less expensive than McKesh (about $100 a pair - do NOT pay more than $125 for them). If you use the search tool on the term "mckesh", you will find LOTS of other information, opinion, and experience.
By the way, Camping World offers a set of McKesh knock-offs. I haven't tried them, but others have done so.
