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.
