All this talk about I do not have the tools or tools are expensive. I did my first fret level with a sharpie, steel wool, carpenters level with 320 grit sand paper rapped around it(still do this today) and masking tape. My first refret job, the only tools I used was a pair of end nips, claw hammer, block of wood, triangle file, sand paper, masking tape, sharpie marker. All those fancy tools make it easy, but they are not needed if you have a little imagination. Buy a cheap pawn shop guitar and have a go, if it turns out try on a little more expensive guitar.
