Do it yourself

BlankDoes anyone here have familiarity with tile saws? I ordered a bunch of tile today for a project, and the woman at the tile store pointed out how much easier my life would be if I had my own tile saw. True, I said, except that I am scared to death of power saws so it wouldn't help me much. (I'm not scared of *all* power tools -- just the ones with big round blades that cut things. Haven't gotten over that -- yet! :) Anyway, she said I didn't have to be scared of tile saws because they don't have teeth (they use a diamond blade) and won't cut human flesh. She swore up and down this was true ... does anyone know if it is actually true or not? I sure would like to know!! Second question ... I looked at tile saws at www.harborfreight.com just now and saw a cheaper one that I thought might work for me. (ITEM 40315-1VGA, if anyone wants to look it up.) Can someone tell me what the real differences are between a cheapie like this and the more expensive ones? I am assuming that the cheapie will wear out much sooner, of course, and perhaps the motor is less powerful so it won't cut as hefty a tile. But my project is limited in scope ... and I figure if I get really hooked on this whole tile thing, I can trade up later. I just don't want to buy a $200 tool for a project I may never repeat. What I want to cut is some marble tiles, 3/8" thick. (I have to apologize for my stupidity about these saws ... but since I am scared of saws in general, I have never looked into it before. But one that wouldn't cut me sounds right up my alley! :) Thanks for any light anyone can shed on this! Ann
