Before I got Netflix, I would have said 10-20. For a while, I was collecting the seasons of The Simpsons, Family Guy, and BSG as they came out, and I already owned full runs of Futurama and Firefly.
But now, probably my answer would be zero. Or maybe 1-3, at best (probably single-season releases like Firefly). I find I generally watch shows again maybe once every five to ten years (with Firefly as the exception, I've seen each of those 2-3 times since I bought it). Since I'm keeping my Netflix sub anyway, I don't have a problem with re-renting them when I want to watch the show again some time in the future.
Since my Netflix sub costs about $1.70 per DVD (I costed it out based on my average rentals during the first six months of my membership), and most purchased series (at least the ones I am interested in) cost $4 (low-end specials) to $10 (HBO series) per disk, it's not really worth it to me right now to buy the DVDs.
You might say (correctly) that in the long run the DVDs will be more economical, over multiple viewings. And Netflix might not be around in 10 or even 5 years. But I think that based on the current pace of technological development in storage and media delivery, by the time I've watched these shows 3-4 times (i.e. 15-25 years from now), we'll have something totally different in place. Probably instant delivery-on-demand of any show ever made to our hi-def sets for a buck or two (today's dollars), but that's just my guess.
For folks who watch shows again every year, I'd say definitely, get the DVD sets... and the lists others have cited are ones that I would agree with in whole or in part.
