A good plumber to install a reverse osmosis water filter?

This may be a longshot but can anyone recommend a really good plumber to install an undersink reverse osmosis water filter in our house? I'm looking for a plumber who has experience with these systems as the last guy pretty much destroyed the water filter.

Recommendations appreciated.

You'll probably find people who've installed them plus high end plumbers and handymen who know how to read.
