Hey Minnesota boy.
Being a carded/loose collector I can take a stab at this. The carded stuff in my collection is quite limited, mostly to items of either higher value or greater visual appeal or imperials. I had many of the imperials on Saga cards, but now the OTC cards simply put those to shame and they've ended up loose, traded or forgotten about.
For loose, I will buy a rehash predominantly only if something has changed. Sadly enough, a minor paint change is enough - Jawas, Tusken, Hoth Vader - I'll buy those. Some of those changes are, IMO, pretty good, X-wing Luke being a prime example with the loss of the bucktooth look. It's annoying to put a relatively new (POTJ) figure aside like that, but this one just looks less goofy, so it's worth the cost. I think I need to grab the POTJ Ben too, because I can't find my loose POTJ Ben

I'm not really keeping a carded set, aside from a few figures - all the Vaders, biker scout, stormtrooper, snowtrooper - though strangely I passed on the Tie Pilot

I've thought of grabbing the Luke's on US cards (Canadian cards are black saga starburst pattern

) but that would about cover it. Just the stuff I like. Were I still collecting all the figures carded, I would be going ape **** over these cards though, they look great.
A little of both. Fortunately I've detrained those completeist urges that others still suffer from.
