I Need Datefeed Automation and some Conditional Features

I currently use Inventory Source for automation of the datafeed I get from my wholesale supplier. They offer several features, but I don't need everything and the ones I do use, I'd really like to have more control over.

I don't like that I am so dependent on this service. They seem to be the only company that does this and I would like to have some kind of software or program or something where I can set up the conditions as I would like them, pay for the program one time and not $50 monthly as I do now. The service also includes hosting, but I am displeased with that service and will shortly go live and find a different host, but it won't lower my $50 monthly fee.

I can go into much more detail if needed.

A DIY option is Pentaho Kettle Data Integration. It can get/use data from almost anywhere and transform it as you wish, then create a file or insert it directly into your db.

Does anybody have any other suggestions? I'm hoping to have some options. Thank You!
