I bought myself a Topdon TC001 last Friday as it had a decent discount .
That has 256X192 resolution. I had a Flir one Pro back in 2020 but ended up selling it. I've been wanting another ever since.
Comparing the Topdon to the Flir, my main thing is the 25 Hz is really noticeable. However, the MSX feature on the Flir made the images quite visually appealing.
My main issue with the Flir was the inbuilt battery which gave me long term reliability concerns and was another thing to charge.
