I need a Duplicator ,help!

Hi, I am down in the States for vacation and visiting my family.
Back home we do wedding and family videos.
We put the long event and a slide-show of family pictures onto 1 4.7 dvd.
We do real quality work but it takes us days to burn 100 copies of it.

What duplicator do you recommend ?

I have been searching the web and found that SuperMediaStore has the best prices.

I plan to burn at slow speeds, 4x or 2x whatever you recommend.

I am looking for a 1-9 or 1-10 or 1-11 duplicator

Which one do you recommend and why.

Don’t need it to be the best in the market
Looking for great quality on a budget

Let me know
