You can also get a membership to techshop.ws where they have cutters among MANY other items.
https://www.noisebridge.net/ hacker space on Mission in SF also had a fairly large 40W cutter... It was not setup for a while - but I think its working now... and you can use that one pretty much free (donate to the space though is a good idea)
Laser cutters are by far the most popular tools at tech shop. Reservations typically fill up 2-3 weeks in advance. Having a hobby machine at home for smaller or recurring jobs could save a lot of time.
