One thing that I'd like to stress is that it's possible to permanantly brick a 2200 if you fail the firmware update. Verify that your RS232 cable is working properly before you send anything through. If it's even a little finicky don't mess with updating unless you have to.
I just added a link in the tutorial to the exact USB programmer cable I use. There's slightly cheaper ones, but I've programmed around 30 or 40 Corio2's so far, and updated firmware on a good dozen or so (including my original/first one, which I probably re-flashed the firmware 20+ times on that one as I was learning to use these) - not a single problem. There might be something wrong with the Corio2 unit, the cable, maybe your computer (less likely of those three).

I hope I get some decent mileage out of it. The menu has 9000+ hours logged so that's a little over a year of operation. Maybe not bad for a 10 year old device?
I think the 2200A that I sold, before I even knew these things kept an hour count (buyer casually mentioned the hours later on) had something like 67k hours on it - and that one has been perfect as far as I know (whereas a bunch of 2200A's with WAY less hours - maybe 15-30k, have given me a couple faults from time to time).

But do all these units use the same scaling engine or do units with higher numbers have improved hardware? I understand everyone seems to use these to downscale up to 1080p to 240p, but how is up-scaling from 240p/480p/720p to 1080p? I honestly like the C2-750 unit, but for some reason they are all $1000 on ebay now.
As far as I know, the scaling is done with the same Corio2 chip - so any model which says "Corio2" should (in theory) have the same exact scaling quality. Differences in models seems to be mostly about the inputs and outputs (the kind, and how many). Some have SDI/HD-SDI, some have audio (others don't), some have the nice DVI-U connectors (little more flexible than the VGA types). I would expect the newer "C3"/Corio3 models to have some advantages, but as those are very expensive I don't know of anybody who has even tried those to confirm they can output 240p to begin with.
For upscaling, I know Xer Xian likes his Corio2 for 480p upscaling. General word is that 240p to 1080p is not nearly as good as something like the OSSC or FrameMeister (which I own those two, so I never tried upscaling 240p with the Corio2).
For 480p to 1080p upscaling, I did finally get my two 2200A's working with my two different OG Xbox's (one outputs YPbPr, the other RGBS), and I have to say I really didn't care for the image. I was using my OSSC in passthrough mode to convert the RGBS output from the Corio2 to HDMI, and at some point in the future will try it directly out of the Corio2 (I was short a cable to try this last time), and I also have a Kramer DVI+audio to HDMI box I can try as well.
