AOC G Line 2nd Gen (AOC CU34G2X). 34" ultrawide with 3440 x 1440 resolution. I believe I paid $450 (US dollars) for it at the local Micro Center back in November of last year.
I really like it, but then I also don't do top of the line graphics / video work nor do I play high end games. Those seem to be the areas where reviews called out the shortcomings. Which doesn't surprise me, given the price. It is easy to spend $700 - $100 for 34" ultrawide monitors, and even more once you go up to around a 40" size.
So I am hoping that more affordable 40-43" ultrawides are available by the time I am ready to get a bigger monitor than this one in a few years.
EDIT: Here is a link to the monitor at Micro Center. I realize you may not be in a location that has a Micro Center store, but the Specs tab has a lot of technical info.
