the best dvd writer ?

[xjapan_hide]

ya i search the forum , everybody said go for pioneer . but i was thinking , if i buy a burner that can burn double layer dvd is more worth it , because i don't have to buy another dvd burner in a year or two . also game are getting bigger and bigger , just like
Ralli Sport Chanlenge 2 on xbox , it won't fit on single side dvd .
any way thanks for your help and suggestion .
