OVAs are also a dying format, Martok. The bottom's fallen out of the market in Japan, and there's much less of a place for them now with the general increase in standards of the TV incarnations.
My favourites?
"Irresponsible Captain Tylor"
"Full Metal Panic"
"Princess Nine"
"Outlaw Star"
"Martian Successor Nadesico"
"Patlabor"
And many, many others....my collection is well past five hundred VHS and DVDs now...
