Well since I have the Pioneer A03 drive I can give a recommendation for it, if all you plan to do is back up data or use it for your own home made movies.
Due to the fact it can only record a single layer it is limited to 4.7GB which pretty much all but the oldest DVD movies surpass.
The price range you quoted is fairly pricey or at least for here where you can pick up the drives for $799 Cdn. now, but if you have the money and want a good backup medium DVD's are alot better than tape drives :).
