Not sure about the rest of you but I was less than impressed with the tool bag that came with my new Fit. If you added a few more items beside the standard stuff, the "buckle" really didn't work so well (i.e. it sucked), and the bag in general was pretty flimsy.

Now I know this doesn't fall into the high tech or go-faster category, but I found a really neat - and cheap - replacement. Disclaimer: I do not I any way represent this company - just found it through Amazon:

Klein 5139L 12-1/2-inch Top Grain Leather Zipper Bag (merchant SKU 5139 LKLE). $21.38, free delivery and in NY, no tax. If you're having doubts from a masculinity perspective, it's very much a "tool bag." Worth checking out...
