We have the KitchenAid, and we have ended up using it far more than we had ever thought. Ours came with a large plastic container (and lid), so basically any time we want to blend small amounts, it's super handy. Makes pretty good bread crumbs too.
pacanis - I use mine strictly like Andy M uses his. Mine doesn't even have other attachments and I don't know that I'd use the others because I have other "tools" to take care of those jobs. Mine doesn't come apart so I simply "blend" a sink or tall glass of hot, soapy water and it cleans right up.
You don't need to spend much unless you just want all that other stuff.
EDITED to say I went to your link - can I now say "I want one of those"? pacanis - this is your fault!
Interesting concept, matching an appliance to your spatulas...
Looks like a good one! I'm sure you'll love it.
