It's a neat product comparison site but it seems to be missing various models. At my first try I already missed the Renkforce 3D printer series from Conrad Electronic (EU/German) (rf100, rf500, rf1000, rf2000). Maybe it's too US/UK-centric?

Extra option could be to check if the system uses proprietary cartridges. (example: da Vinci)
