Inkbird are cheap as can be and I have used them for years without them themselves failing. I double up on them to prevent overheating just in case, and it saved an entire rack of 14 (8 were gravid) adult females a couple months ago because a probe got dislodged somehow. That $25 extra bucks saved me thousands of dollars and a lot of heartbreak.
I've had great results with Herpstat as well. They are on the pricier end, but still not outrageous, and they do have some really nice features. These would be my preferred choice over inkbird for running CHE or RHP. I still use Inkbird as a backup with my Herpstats.
If Herpstat is a bit outside your range right now, Herpstat + a backup definitely is. I would grab two Inkbirds for now and upgrade the primary to Herpstat when you can if you really want one.
