There's a huge difference between 920 (GSM) and 822 (Mainly CDMA), 920 being a flagship, has Optical Image Stabilization (OIS) and other things.
I'd like to point the fact that 920 is a bit old now, I'm not saying its ancient but there are devices available now which are more powerful than 920.
You might want to look at Lumia 925, since you are looking for refurbs/used it should cost somewhere around $200~ you'll be stuck with 16GB device memory though (No expansion slots).
If you're comfortable with that I'd seriously advise you to go with 925, its made of aluminium and looks pretty slick, the only thing I don't like about it is the memory part, but its just me, I know people who still live happily with a 2GB memory card on their phone.
If you look at Ebay you should have no problems finding it at the right price.
Let me know what you think.
Edit - Oh boy, you are the same Incipio case guy, I just disappointed you on your incipio thread lol.
