Well, I guess you need to decide what the convenience is worth. An ink cartridge dries out in 2-3 years and toner can last a decade or more (I honestly don't know, ours finally ran out after 8-ish).

Laser printers aren't that big, mine (B&W with scanner) is about a piece of paper and a half in all directions. I got it for $150 or so on a sale from Costco (currently listed for $250), and it like like the color version is a little taller but similar footprint (but also more expensive at just $390). Official dimensions of the Brother color laser printer (MFC-L3765CDW): 16.1 in. x 17.5 in. x 15.8 in.

I personally know need B&W, and if I needed color, I'd just go to the library since I go almost every week anyway.
