The lockable bin is a great idea, I wish I'd thought of that when I lived in a condo. I'd make sure the fact that you have a locked bin in there is not visible from the outside, or it will attract thieves like rats to garbage..
No problem, my storage locker has a section that is hidden from plain sight.
If your looking at a new dry suit, I would check out Divetank Dive Shop: Store Home. .
I know those guys. I bought my 3mm full suit from Richard. I went to his office and did the transaction in person. The wait for my suit was fine (because I ordered it far in advance before I needed it) but some aspects of my experience with them was not that pleasant but was not that awful either. Yes, can't beat Richard's prices. My LDS was not too happy when I mentioned that I bought stuff from DiveTank.
