Import DVD's

[Franky]

I'm a bit of a dvd nut and so far have built up a bit of a collection of movies and lately a few series dvds. I have the first 4 seasons of Frasier and want some of the later series but have found absolutely no info on when they are to be released here.

Anyway my question is about perhaps buying them from overseas as they are avaliable, I know all about regions and know that they will work i'm interested whether or not it'll be worth it from anyone who has done this before. Is it cheaper to buy a number of seasons at a time or get them seperately and how much would shipping be? is a online shop like amazon the way to go or is ebay about the best option?

Any help/ideas?
