One of the most useful "cheap" tools I have found is the $19.99 reciprocating saw. I have had 3 or 4 of these over the years. (Yes I consider them "disposable"). For a 20 dollar bill I can use, abuse, destroy, and do it again a few times. Then I go buy another. They ussually last about a year or so, depending on how much abuse. This past "time to replace", I decided to get a Ryobi one, 1/3 more power, some nicer features... What a POS !... First time using it, broke the blade holder... Took it back the next day and got another... 60 miles RT (had to get other materials anyway). The second wasn't any better, the reciprocating shaft would bend when any pressure is applied (and I mean just a little). Got another $20 special (really $16 w/ 20% off). Serves my purpose well. I think I'm gonna try the next better "industrial" one next time around.
