Hey Pierre, those are the ones I'm looking at. Only negative I could find is from photogs saying that, if you aren't happy with it's auto calibration to a printer, you have no curve control and then must adjust curves manually in PS. That would be maddening for a photographer but I see little need for it for us screen printers. It sounds like all these are the same basic hardware with the more affordable ones being short on the software features that some may want. I do like that's it does both reflective and transmissive. If you're happy with I'll go for it.
