Bonanza: I bought season 4 vol.2 and season 5 vol 1. I did this to get my favorite episodes of Bonanza.

If I had it to do over:
The Wild Wild West - Season 1
Mannix - Season 2 only
Mission Impossible - Seasons 1-3
Star Trek - Seasons 1 & 2
The Avengers - Emma Peel seasons
Voyage To The Bottom Of The Sea - Season 1
Naked City - Half Hour, Season 1...Hourly, Seasons 1-3
