Yep, doyd, plexiglass can be cut with just about any saw. It does crack though, so I'd recommend having it cut to size at the store. Home Depot and Menaard's have standard cut sizes available. When using a power saw, be mindful of the melting factor and try to cut fairly quickly. I've even used a jigsaw on it with decent success.

The only thing is, that it scratches very easily, so beware of what you use to clean it, you may find yourself with a streaky, cloudy look in no time.

How exciting for you, a new kitchen is such a joy!
