I definitely enjoy making my own gear. Plus, I don't have to pay for the cans, as my roommate drinks way too many sodas. Another friend gave me the sand paper (she bought a pack and needed one piece) and I've already got a pocket knife. So my stove attempts only cost me some fuel, which I would be needing anyway.
At this point in my life I need to save all of the money that I can (college student about to get married) so while I might have some free time, I definitely can't afford any extra cost.

Of course, going full circle, I love making stuff, so the DIY gear is for me even if money was no issue. I'd just start with nicer materials! <img src="/forums/images/graemlins/grin.gif" alt="" />
