Reverse osmosis recommendations please!

[EightFingers]

We have a well and I'm the thinking of a reverse osmosis system for drinking water. Right now we get our drinking water at the Keaau transfer station. I don't want a whole house system, just something that will fit under the kitchen sink.
I want:
Something reliable,
Reasonably simple to install and maintain,
Filters easily obtainable.

Thanks for any help!

Might want to take a look at Berkey filters as a possible solution. Simple, effective, affordable.
