there are still lots of titles not available on dvd that you can get on laserdisk. It definatly beats vhs. I would only get a ld player if I wanted alot a these titles or if I already had a huge collection. If you're considering it on the first grounds you also might look into a region free player. Lots of stuff not available in the US is available in other regions, and a decent region free player isn't too expensive. Plus with a region free player you can have more superbit titles, etc.
$10 isn't that great. My average privce per dvd including shipping and everything for my last 7 columbia house accounts is around $7.80 and thats for brand new stuff. And I don't even have to get up. Except to get more beer.
