[buffylover]

I want to buy some high quality dvd copies for X'mas gifts.
such as
star trek voyager (http://www.dvdsetshop.com/CommendProduct.aspx)
the sopranos 1-6 (http://www.dvdsetshop.com/CommendProduct.aspx)
scrubs 1-7 (http://www.dvdsetshop.com/CommendProduct.aspx)

I wonder which one is better for my mother-in-law?
