This is worth picking up to anyone that hasn't seen the show or has but doesn't own it on DVD already. Unfortunately I own the first two seasons on DVD, so I'd have to see a price of less than $20 per season for me to double dip. I'm hoping this goes on sale sometime around Black Friday, either individually or as a set.
Plus the two seasons are available to instant stream on Netflix and I'm sure seasons 3 and 4 are coming sooner or later.
