I've just finished ordering most of the parts for a 2022 ABX run. The good news is that, I think, I've found most all the parts, or part equivalents, and nothing is back ordered. The bad news is that some of the parts have gone WAY up in price. Worst case is the (now obsolete) display going from $30 to $80...but at least I can buy it for $80.
We don't know what the price will be yet, but it will be higher than the previous $1099. Expect the ABX box to be available in early 2022.
