Leo, to be honest instead of asking others to look for you, why don't you go look yourself? It's not hard. There are dozens of printers available for under $100, some for $50 or less. You can Google "printer under $100" or check shopping sites. Newegg.com lists 85 printers for $100 or less. There are quite a few $50 or less.
As far as what's a good printer, 99% of people need just a regular color inkjet (and to be honest most of those really don't need the color). My main buying consideration is how the cartridges are used, I prefer a separate black cartridge.
And in the spirit of new information, what do you consider to be a good "regular old printer", and are such printers available on the sub-$100 end of the cost spectrum?
No sarcasm, no flippancy, merely a genuine request for information.
