Extech i5 or Fluke IR-Insight vs Fluke Tir

[Bob bias]

Hello. I'm debating between buying a used Flir Extech i5 or a used Fluke IR-Insight for $1500. Which of these is better for general purpose thermography? I may even consider a used Fluke Tir, but that is higher priced.

I like my Fluke, but it does get HEAVY after 30 min or so on holding it out at arms length to see the screen - something to keep in mind if you intend to use if for extended survey work.
