Cellaring for the not-so-wealthy

[Caesar]

Has anyone had any inspirations for where to cellar wine when there is no cellar to be had in your house? The closest thing in mine is a crawlspace with uncontrolable temperature in the winter. The upshot of this is that I am unable to invest in "steals" when I find them at times(example: 1995 Lafite at $45). Well, actually, I did buy that one, but turned around and sold it out of fear that I could not do it justice through aging, and my concience wouldn't allow me to just keep it and let it go to hell. Any ideas sure would save a lot of frustration. Thanks!
