Here's a decent price on a 1:1 duplicator:

I generally look at known media stores for a duplicator.
In the UK, that's
SVP.co.uk. In the USA, it's
Meritline or
Supermediastore.
After seeing what is available, I see if the
Amazon stores have better prices.
SVP had this:

HOWEVER, the price at
Amazon.co.uk is better than SVP on these devices!
Duplicators are not cheap. They usually run about the same price as an inexpensive computer, because that's essentially what these are -- single-task specialty computers. Not much different than a DVD recorder, in this regard.
Most duplicators are also just the "controller" and maybe a DVD-ROM/CD-ROM. You have to buy the burner drives separately. In some cases, it's even wise to replace the DVD/CD-ROM with a burner, too. Most read-only drives tend to be crappy at giving a quality read on a burned source disc. I'd suggest using Pioneer or Samsung drives, too. Maybe Sony Optiarcs. Not LG, not Plextor, not Liteon.
