QTR-Quadtone RIP

Hi,

I read the Quadtone RIP user manual. I want to buy a photospectro- or densitometer. To measure densities, linearize a Quadtone RIP and making ICC profiles. I looked at the Colormunki Photo, Spyder Print, I1 Pro, .. but they are quite expensive (to start with). I read in the Quadtone RIP manual (2005) about the use of X-Rite 810 densitometer. I found them very cheap on Ebay. Are they usable and trustable, or is this technology to old and do you advice to use newer gear? The X-Rite 810 works via serial port which I don't have anymore on my pc (very new one). But I guess there is a workaround for that.

Thank you!
