I think they're pretty much all going to be the same in terms of ease of disassembly, seals, etc. I bought an all stainless model from Keg Connection for a decent price.
Make sure you clean it well every once in a while. I like to remove the beer nuts / MFL fittings and gaskets, put the coupler in the "open" position and put in a bowl of hot PBW solution for an hour or two, then rinse really well and put in a bowl of very hot water for another hour or two to make sure it's completely rinsed out. Then reassemble and make sure to hit the main gasket/seal with keg lube.
Should last a long damn time if you maintain it! I like to spray Star San through it and re-lube the main seal every time I tap a keg. I think lubing that seal will make it last a lot longer.
