For all you TPB/GN collectors out there, how did you start your collection and what are your current buying habits? I've been thinking of selling off my collection of single issues and using the money I get to build upon my TPB collection, this will help to conserve space and I'd be more prone to read my stuff since I wouldn't have to find the books I want to read and take them out of bags and boards and then re-file them again.
So, when did you make the switch, and why? And how did you build your collection?
