There are actually two good quality complete sets floating around out there.

There's one called the "Studio Masters" set which was made directly from VHS tapes given to cast members of the 1989 Batman movie. The episodes are uncut, free of onscreen logos, and contain the "In Color" bumpers at the beginning of each episode as well as the "Next Week's Villian" bumpers before the end credits.

The other one is the "Canadian TV Land" set that was recorded from a marathon broadcast of uncut episodes a few years back. It sports superior picture quality over the "Studio Masters" set with a few very minor drawbacks. There are no "In Color" or "Next Week's Villian" promos and the "TV Land" logo is seen in the bottom right corner of the screen through most of each episode. Since it's CANADIAN TV Land, the logo is just that... a logo. Not like the one on TV Land in the US that's constantly animated and letting you know what show you're currently watching, what's on next, and what movie will be playing the following week.

Both sets are worthy of having until an official DVD set is released, but like Disney's "Song of the South" that may never happen.
