Tile Saw: Rent or Buy?

So we’re going to be re-tiling the bathroom walls, with 18” tiles set diagonally, and with narrow grout lines.

All recipe for “holy *&^%$# that’s gonna be hard to do”. And I haven’t done a whole lot of tile.

The local rental place has a “tile saw”, no real identifying information, for $65/day.

Craigslist has things like a Imer Combi 250/500 Bridge or an MK Diamond MK-100 tile saw, used, for $500.

Do we do this with a rented tile saw, or do we buy something like one of these, use it, and then sell it?
