I've always used the best products out there and some of the shit on the 'market' is simply a reflection of the customer base, be that dog shit apex seals for $300 or nintendo game boy compression gauges powered by portable dildo batteries !
When my OG unit dies I would consider ones like this (if still around)..
This is the one I currently use, been with me for 10+ years and its great! corrects to cranking speed and can log too if you need it, switch units on the fly and works on piston engines as well with long reach sensor to get inside twin cam heads.
