Hi,
Been through the same dilemma looking for a 27.2″ dropper…
I had the older version of the Pure post (K850i? – I think) and it too died after a couple of months. After that I found something called an “All Mountain Post” from Precision Cycling Components advertised on the STW classifieds (only available new from the USA – http://www.precisioncyclingcomponents.com/ ) so I got that. It lasted about 18 months before the remote broke. I bodged a fix using an old, pre-indexing, roadie gear lever (ugly as sin, but it worked) and started saving for a Gravity Drooper.
I’ve now had the GD for a couple of months and (not wanting to tempt fate or anything), it’s been fine so far. A bit clunky, perhaps, but pretty intuitive and seems to have exactly the right amount of travel for any situation (I have the 3 + 1 version).
Incidentally, I think that one of the other – grossly inferior – mags reviewed seat posts this month, which included another 27.2″ make that was new to me. Unfortunately, as I was skimming in the newsagent and didn’t buy a copy, I can’t remember the make. Might be worth having a look at (or dropping an email to the editors at) MBR, though.
Sorry for the rambling reply. Hope it helps, anyway.
