I'm a bower bird, by nature, both my parents are. I'm slowly learning to move on stuff that I no longer have a use for though. I recently sold a third party Outback to a guy and enjoyed a week later seeing him post up pictures on a facebook group he had taken with it in an outdoors setting, it looked great and was being used for much more than I ever had planned for it.

I'm also a tight arse and wouldn't be able to bring myself to rent offsite storage for my collection.

I think there's a lot of truth to what Sinnertwin said. I love book s though, and just because you haven't read something in a long time doesn't mean you're not going to read it again. but perhaps you're better off having a lot less of these in your possession and re-buying them when you want to read them, or getting a digital version and decent digital reader, especially if you do this with a lot of comics.

the off site storage during renovation is a completely different thing and if you can't fill up a mates garage or spare room for the period, offsite storage is completely valid in that case. Having to move all your heavy stuff may also sway your opinion of how much you want to move back in once construction is finished.
