I wouldn't feel bad about it, it's a shitty design to have 700 or so unique items, on top of random items, components(which aren't really a big deal anymore since they became stackable), pots, quest items, recipes, etc then only give you room to collect a small amount. Even people in the official forums who say they don't want a bigger stash size do the multiple transfer file route.
Doesn't make any sense to me, but the main Developer said when he plays games with big stashes he doesn't have the discipline to not store everything he finds, then he ends up stressed out about the mess. Personally I'd like to see stash tabs purchasable with Iron, so people like that can just choose not to buy more, and people without his problem have all the room they want for a price. One more thing to grind for in my opinion.
As it is now, I've been waiting impatiently for release and mod tools so it can be fixed.
