Unfortunately most of them are terrible. I've played with it on and off for years and even gotten individual tools for $100+ but still have issues. It's a bit of a mess with PAL/NTSC, different recommended settings, and at the end of the day you still need a high quality VCR to extract all the data. Those tend to go for hundreds of dollars here. You also need a time base corrector (some VHS have them built in I believe) to avoid dropping frames and causing desync.
A common suggestion is to just get a VHS->DVD recorder and then rip the DVD. You lose out on quality but it usually works and will save you a ton of time.
The suggestion by OP is probably if you truly want to maximize the quality.
The whole point of VHS-Decode is to bypass as much of the VCR's output circuitry as possible; capture from the read heads and apply modern digital reconstruction from there.
There are some high end vcrs that can do a better job (according to those who have them.) but they are getting old and even broken ones can go for a couple hundred on ebay.
For home movies it isn't worth it since the starting quality probably isn't that great. I've messed around with it for a couple movies that were only released on VHS.
