I firmly believe that Squiers can sound as good in a recording as any other guitar out there. I also don't think it takes a lot of money to properly document that "sound". It does however take at least a little investment to really showcase your talent; burgeoning or beyond. With that in mind... SM57: new (I can't typically recommend buying used mics from anyone but a professional broker but the SM57 ain't that kinda mic; just get a new one). Tascam DP-008EX: Buy used (it's not mechanical so barring some drunk DB spilling a beer onto it or a knucklehead using the wrong AC adapter you should be fine as long as you can return it). Monoprice 15-Watt, 1x12 tube amp: (I don't see many used ones for sale so wait for a discount or open box from Monoprice; a couple of times a year there are some serious sales). Used programmable drum machine (I recommend the SR16 because it was the last one I used that didn't completely suck but that was a long time ago and there are so many available since then that its crazy; dime a dozen it seems). With these four components I can't see why anyone shouldn't be able to record awesome sounding demos without booting up a computer till uploading. I know what most will ask... With patience and judicious shopping it'll cost about $500.00.
