From my reading, the 100 is a better printer, and much less expensive, than the Pro-10. The latter is pigment ink...Pro 100 is dye ink.
Here is some info on the Pro-100 - which can be found for $100-$150:

It never ceases to amaze me how quickly the DpReview threads on the Pro-100 turn towards recommendations of using third party refill cartridges and ink. Kind of like buying a Ferrari, and then deciding it's imperative to then save money by filling it with 87 octane fuel.
I have not tested a third party dye-based inkset yet that delivers more than about 1-2 Megalux hours of light fade resistance on any media. That's approximately 1 year on display to reach easily noticeable fading at the often cited Willhelm 450 lux daily average illumination level. Of course, one can find rooms in a typical home that drop down to a museum illumination level of 50 lux or less, and under those circumstances, the fugitive print will then take about 9 years on display to reach easily noticeable fade. So, many recent converts to third party inks are quite happy with annectdotal stories that they've had their prints on the wall "a few years" and have seen no fading. Just give it a few years longer. It will get there sooner than you think
All that said, the Pro-100 will deliver best in class dye-based print longevity if using the OEM cartridges, better than Epson Claria (due to the photo gray inks stabilizing the low chroma colors) and definitely better than traditional RA-4 chromogenic color paper like Fuji Crystal Archive II. Depending on media, prints made with the CLI-42 ink set in the Pro-100 will reach the 30-40+ Megalux hour lightfastness range, as much as 50x better than third party inks.
And, as an owner of a Pro-100, I do think it is indeed a great little printer. I have a Pro-1 and an Epson SC P600 (which is the little brother to the p800) here in my lab as well. All great printers with excellent reliability so far. The P800 is going to ultimately give you lower cost of ownership, but to get there you will have to print several hundred 8x10 equivalent prints or more, so if you don't need the larger sheet size, and don't plan on making a few hundred prints per year, the Pro-1 (or the Epson SC P600) probably makes more sense. Also, the Pro-1's clearcoat definitely reduces bronzing and gloss differential compared to the Ultrachrome HD ink used in the P600/P800 models. It's not 100% perfect, but when used in the "overall" rather than "auto" clearcoat mode, it gets pretty close on a wide variety of glossy/luster media. The auto mode really should have been named "economy" clearcoat mode because it puts no clearcoat down in the white/near white areas of the image, thus leaving differenital gloss problems even as bronzing is reduced. Anyway, if bronzing and gloss differential bother you, and you like printing a lot on glossy/luster media, the Pro-1 is probably the way to go.
best,
