Based on the good advice I got here, we decided to tile above the kitchen countertop to beneath the cabinets. I don't want to rent a wet saw simply because, for me, these projects take time, and the rental will add up soon to a price of a new saw.
So, how are the inexpensive saws sold at Home Depot, Harbor Freight, etc? The area to be done is not big at all, and we bought the prebacked subway tiles (2"x4").
