I have a DNN site in which people can order digital music downloads. I'm using the Digital Download Locker feature of Cart Viper to implement this. Does anyone know of a customisable download manager that people can use to manage their purchased downloads, similar to those available on sites such as linnrecords.com, the classicalshop.net etc?

Many thanks for any advice.

I have no particular suggestions, but wonder what you do not like in the Cart Viper product.

I have found Nigel at Cart Viper to be quite helpful at adding custom features for "reasonable" prices.
