I spent $400 on a cheap scan tool and it burned me bad

I picked up one of those $400 Autel scanners off Amazon thinking I was saving cash over the $2000 Snap-on models. Last month I had a 2015 Ford F-150 with a weird intermittent misfire and this thing showed me a generic P0300 code with no cylinder specific data. I spent three hours swapping coils and plugs on the wrong bank before I broke down and borrowed my buddy's high end Matco scanner. That tool instantly showed me the misfire was cylinder 7 with live misfire counts and a weak injector waveform. The cheap scanner literally cost me an extra day of labor and I still ended up buying the expensive one anyway. Anybody else get burned by those budget scan tools or is there a specific one that actually works for modern diagnostics?

Man, I gotta disagree a little bit. Those budget scanners have their place if you know their limits and don't expect them to do everything a $2000 tool can.

But see, I look at it the other way. A cheap scanner that can't even tell you which cylinder is misfiring is basically useless for anything beyond reading basic check engine lights (and even then, it's sketchy). You spent $400 on a tool that lied to you, then had to spend real money on the right one anyway.
