I started collecting a few years ago and obsessed about everything being mint and complete, but for me the cost of doing this began to dampen my enthusiasm for the reason why I started collecting in the first place - I loved the figures as a kid.
Collecting some of the figures for the sake of it became an expensive chore rather than fun. Yes mint and complete is cool
but they cost a lot these days, with the exception of capes and a few sabers, most of them are pretty fiddly and annoying. Obviously the value is tied up in accessories since they are harder to get than the figures, but if you are collecting for fun rather than investment, you could have a lovely complete set of minty loose in a great cabinet at a fraction of the cost. It does seem rather perverse that a complete set of accessories is more ‘valuable’ than a set of minty figures without accessories - I know which i would rather have on display!
I do not touch repro stuff, but it is up to the individual what they buy for display purposes - the broader issues are that they are inevitably sold as genuine, the proceeds go towards making better repros, and they devalue genuine collections as buyers lose confidence as it gets harder to spot the difference. For these reasons I avoid repro.
