I was lucky. The granite shop owner, who tolerated the 40 year old kid (thirty some years ago) gave me a lot of tips that saved me money. At the start, and per his advice, I bought a Makit circular saw and dribbled water at the kerf to cut his scraps down to usable pieces.  It worked wonderfully. 

Later, he talked me out of buying the more expensive tile saw (3k) for the much lessor beast I yet have, which is fine for the play I do.

Getting knocked on your butt by a bit of water getting to an electric saw or grinder aside, I, ALWAYS, will take electric over gas.

Okay, then there is the electric car thing and that just isn't going to happen.
