So i managed to get an improved version of Seek Thermal (standard non-xr version) for 170$ (used, sh).I think it's a 2017 version, it has a manual focus ring, which is a pretty big deal.Compared to what i was used to seeing in the old version with fixed focus, which was more of a smudgy mess, this is a huge improvement.It can also focus up to 3cm.For this kind of money, it packs quite a punch.
