Agreed. The Toneport looks good as a combination amp modeller/audio interface (it includes guitar and bass amp models, which is cool) but I think the extras that come it are, well, dodgy freebies :)
If you want to have decent drum machine action, you can probably find a solid shareware drum machine application that won't cost much (on my Mac, I use Doggiebox, which is about USD 40, and there must be similar apps for Windows machines) and the free ns_kit samples from naturalstudio.co.uk. Google or hit versiontracker.com to search for drum machine apps. A bit of a learning curve involved in doing your own drum programming, but worth it -- you'll get much better drums than you would with the Line6 thingy.
