I'm in the market to replace my split-system heat pump A/C. An installer came by today and said that there is a "new r22" that eliminates the need for the expensive puron (r410). I googled and couldn't find anything about this "new r22". Has anyone read anything about it?

Look for R417a a direct drop in replacement for R22.
There is also R407C, R421a, HC-a22 and a few more.
I haven't used any alternative to R22 yet so I can't
comment on it but I have used R416a in place of R12
and it's doing a good job. I haven't had to install
or service any Puron systems yet but may have to soon.
