I have exactly this printer, which I bought last summer for $180 via Costco, except mine says "Xerox Phaser 6100" on the front. So far as I can tell, they're absolutely the same printer. Thanks to the built-in Ethernet, I've got it in a hall closet around the corner, where it's using a different electrical circuit than the one in my office. No more lights dimming when the printer warms itself up.

Like you, I use this thing rarely, but when I use it, I'm very happy to have it. Color is excellent for printing Google maps and the like, but I wouldn't use it for photos. The only thing to take care with is printing PDFs that use greyscale. The printer tries to render the greyscale values with the color toner rather than the black & white toner. Not only does it look funny, but it also takes longer to print. As such, if you're printing something that uses greyscale and you want speed, tell your printer driver to switch to black&white mode.

Amusement: the printer has a web admin interface. You can set a password if you like, but so far as I can tell, it never actually asks you for the password subsequent to that. This printer really needs to be kept behind a firewall...
