Hello, I've been searching for an EHiem 2126 at my LFS and online and I cant find it!!!

So I was wanted to know where I can buy it. Here is the list of stores that are around my house: Petsmart, nnnnnn, Petfun, Pets and ponds, and Petco. If anyone bought their Ehiem 2026 from those stores please tell

Also if anyone bought theirs off the internet, where did you buy it? Also I know for sure that my petsmart has the 2126 and 2128, is it the same thing as the 2026? Here's the link:
the 2126 and 2128
