The 10-22 prices I've seen have remained stable. Many stores are out of stock, but they always are at this time of year. They are always a common Christmas gift and stores don't like to restock until after they have finished their year end inventories.
The 10-22's made in recent years are far better than the older versions. I've owned and used them for close to 40 years, they have always been 100% reliable, but with at best average accuracy. The last 3 I've bought/used made within the last 2-3 years have been far more accurate. They shoot just as well as my CZ.
They replaced the cheap aluminum trigger group with a better, stronger trigger group. Some seem worried that the plastic is a downgrade, but it is actually touger than the one made with aluminum it replaced.
Give things a few weeks and you shouldn't have any trouble finding a 10-22 at a fair price.
