Assuming they're spread out over time, and available for some time (like years), I love them enough that I'd probably buy a wave/set per year... That's assuming it's like one set available at a time, and not all that dumped at once.
All at once, i'd get picky I think. The more unique it would be, the more likely I'd be to want it and pass on the rest if they're too similar to existing ones. Which someo f those are pretty darn close or possibly exact.
The purple R3 dome though, that'd be something I'd want, so that on a purple body/legs would be neat...
Some of those sound very similar to existing ones though, and the pic seems to back that up, so yeah I can pass on one that basically looks like R2-D2 or any of the Queen's droids. A lot of those could be easy passes really.
That's, of course, assuming you build a figure individually and don't buy them by the set. There's so many variables to it right now.
