Manual span for <$300?

[ifonlyeverything]

I'm looking for a "gun style" thermal camera for ~$300 that allows for a manual span. I currently have a Topdon TC004 and its resolution and frame rate are acceptable for my use (PCB repair)... but it won't allow for user defined/manual spanning. Right now the Guide PC210 is on sale for a little under $300. Is this still the best (or only) manual span device in my price range?

edit: I guess I am not totally beholden to "gun" style cameras. The Infiray XH09 and T2 look interesting because of manual focus...but does the software support manual span?

The Hikmicro Bxx range (and ECO) have manual span. I don't know about the US pricing.
