I did! I have been getting by on my £50 Samsung ML2165W for a couple of years, even with the starter toner I think. The replacement toners are more expensive than the printer, mind you.

It starts quickly, prints well and is really really small. It isn't AirPrint enabled, but they do offer their own app for iPad / Android, and it works alright for me from my Mac OS machine, so I am happy.
