Basics re switching to hydraulic

All our road/moutain/commuter bikes are either caliper, V or cable-disc and I do all our building and servicing myself. I've never tried hydraulics although I understand the principles because I service our motorbikes too.

Question: We fancy trying out a front hydraulic disc on one of the moutain bikes and since I will continue to want to do all the installation and servicing myself we wonder if there are any that people would steer us either towards or away from in terms of ease of set-up and servicing while I learn this extension of the craft?

The bike I intend to experiment with has a 160mm cable disc on the front currently with a 6-bolt rotor and a Rockshox Duke fork with a non-post type mount. While I'm at it I might as well increase the rotor-size if I can.

PS Since this is mainly an experiment at this stage I'll be looking for something used on eBay I hope.

PPS Absolute performance is not an issue - we've no descents of Everest planned.

So any thoughts on what would be easy to get hold of, good availability of installation and set-up info on the web, don't fall to pieces if you service them yourself, servicing kits easy to get hold of, not silly expensive?

Thanks
