Are there printers that use just one b/w ink cartridge and one color cartridge at the same time?

I want to buy a non-expensive inkjet printer and I keep hearing of printers with 4 cartridges, etc. Where I used to work, the printer only had two cartridges, one b/w and one color. I forgot the name of that printer. Wouldn't this kind of printer be a better option (less ink to buy)? Or am I wrong?
