I have to say, I got a bit bored as my loose run started to come towards the end, the last few loosies took a bit of saving so went a few weeks/ months between purchases, but one thing that really got me interested was displaying my stuff.
I work in retail and manage 11 shops so display is something I think about. I picked up 2 ikea deltofs (highly doubt that is spelled correctly) and tried by best to make dioramas and make them as visually pleasing as possible, so even people who don't follow star wars could see what was going on. it really captivated my, got me looking online for ideas, and picking up stuff I never thought I would want, such as surplus ewoks and bespin guards.
every day or so I was opening the cabinets, tweaking the positions of figures and ships. it was a lot more enjoyable than just lining them all up on Perspex shelves. I don't have any photos (yet!) but to give you an idea:
I have Tatooine on the top shelf, with the cantina set up with patrons, greedo and han talking it out, lukes speeder stopped out the front with a few stormies grilling him and c3-po. also have an xwing squeezed above.
next shelf has the battle for hoth, rebel troops and tauntauns verses empire troops with radar cannons and tripod lasers, plus a snowspeeder and a wampa watching
next shelf has lando flanked by lobot and some bespin guards greeting han, leia and chewie at their arrival to bespin, backed by the cloud car and some ugnaughts looking on.
bottom has the battle of endor, with the AT-ST, two speeder bikes, ewoks, scout troopers, pruneface, han trenchcoat and the other endor rebels, all fighting it out.
I had as much fun trying to find scenery and accessories that would compliment the displays but not take away from the kennery goodness, such as Playmobile trees and ferns for endor and all the mini rigs, which I had mostly ignored up until then, but fit in surprisingly well in some situations.
this is just one of the two cabinets, ill type up the other an do some pictures for the showcase once I'm happy. the best thing was my fiancé finally got what I was trying to achieve with my collection and stopped winding me up about my expensive space dolls, my family and friends commented on how it looks like a toy museum display and several seemingly random figures they had no idea who they were suddenly became clear (such as the AT-ST driver, cloud car pilot etc..)
sorry for such a long reply but I'm sure you see my point, as mu signature says, you don't need to be spending thousands on minty sealed boxes to enjoy yourself.
I prefer trading items to buying them, have a loose run, about half the ships/vehicles and all the mini-rigs, spent under £200 and have had a blast doing so. This hobby doesn't have to be about spending a mortgage deposit every month on one item
