Anyone pick up a set somewhere they are happy with?

I have a dog that likes to sit in the pass position and I can never use that
mirror where its located.
It like to put on those mirrors like fastforward.ca has, but I don't exactly
have a spare $320 for this project. (not that those aren't nice, of course,
I just don't need them THAT bad and I know there must be some JCwhitney
style ones I should be able to pick up for about 1/6th the cost.)

thanks!
