2 questions: DVD-R and DVD copier..

[Johns]

I am lookin to purchase a DVD-R that will record in Best quality possible(closest to DVDs sold on retail).. anyway I cut it down to 2 systems, the Panasonic DMR-E500HS or the Sony RDR-HX900?
are these systems any good or are there better ones out?

Also I am lookin to purchase a system that will make mulitiple copies of a DVD, but have no idea of any??
