I agree the video quality is not good, but I purchased them a while back just to have. Sure, some content is online in places like YouTube, but there is NO guarantee that videos will remain online forever. Any channel creator on YouTube can pull a video at anytime. I think it comes down to what value at what cost for each individual.
For me it was worth it, but if someone else wants it and really can't afford it they can try to find the appropriate video on YouTube and there are tools to copy that video down to your local computer. I'd recommend doing this, if you really want to keep it. Similarly, I absolutely can NOT see enough value in the PowerPro for me at $2k, but if it were more like $1k, then I could stomach it. Other members think I am crazy and that $2k for a PowerPro is money well spent. Similar arguments can be made pro vs. con for the 520 table system upgrade, the "new" PTWFE book, etc.
My guess is these were recorded on a VHS type camcorder at the time, so the source material is NOT going to improve (only 240 scan lines), i.e. they can't remaster these and improve it. Unless someone else is going to re-record them and star in them, this is as good as you are going to get. Any volunteers to be the next Nick Engler??? Perhaps Mr. Gale could be willing...that canoe movie was top notch!
