eh, if its out, then I would rather buy it then rent it, however there are limits to what I am willing to spend, usually NO MORE then 2 bucks an ep (we are talking anime there) and thats only if the show really catches my eye, usually dont want to spend more then 1.50-1.75 an ep.
and then there are movies, unless its some uber super deluxe edition, please dont sell it for more then 15 bucks.
