Thanks Mate, yeah dust etc can be a problem if sets are on display for a long time. However I have rotated my sets on a regular basis as I have collected so many sets over the years. In fact most of the figures and tanks etc spend most of the time in their box packed away in wardrobes etc.
However, due to recent escalating health issues I have reluctantly decided to 'bite the bullet' and sell most of my collection. I've spent the last few days digging out all the sets to decide what to sell and what sets I can't part with. I've found some sets I had forgotten I had, as well as empty boxes that I didn't know I had. Now the hard part about deciding what to sell and what few sets I 'must' keep. However, it's like selling your kids, what sets do you choose to sell, and for how much?
