That's up to you to decide. I've paid a lot more for video instruction. I've got stacks of VHS tapes and DVDs, and plenty of video downloads on a whole variety of subjects. For me, it's about new information. If I get one or two usable things out of a lesson, to me it's worth it. I buy plenty of books too. Some of em turn out to be clunkers, but one good one makes it all worthwhile. Everything from travis picking to chicken picking to swing to jazz to improv to 101 country licks to dobro, clawhammer banjo, etc. I love it. I love getting new information that makes me a better musician.
But that's just me. Everyone's different.
