Buy if:1) you have the money2) you need the flexibility of being able to watch them when you want to watch them3) you will watch them over and over again4) you want the sense of ownership5) add other factors hereOtherwise, borrow them from the library. A good strategy would be to borrow first and see if:1) you really have time to watch them2) you really enjoy watching them3) you really want to buy now that you have already watched themI personally buy (but don't watch very often due to lack of time). I don't mean I have a lot of money to spend. It's just that here in HK, we can buy the China editions of DVDs, which are very cheap (US$3/DVD). It is completely legal and the content is just the same. The HK editions are like US$15-20, far more expensive. I have already collected 64 titles so far. Nearly all are piano related. I have been trying to find "Horowitz - the Last Romantic" without success. I am prepared to pay quite a bit if I can find it .....
