Here is a quote from my pinned Tools thread:
"Keep in mind that certain tools listed may have other uses to you, not necissarily in guitar building, so keep that in mind when deciding what tools you will be acquiring."
If you think you'll get more useage for your money by buying a jigsaw, then do that. Yes a jigsaw will work, just not as well as a bandsaw.
BTW, I don't have the pictures anymore, but before my older sister moved out, I had my tools in my BEDROOM. I converted my desk into a router table, leaving all the drawers in place to hold stuff, and had my 8" bandsaw positioned on the router table, and at one point had my 8" drillpress sitting on my dresser!
