Last year my ever-indulgent wife got me Seyco's small dust collection system for Valentine's Day. It counts under our rules, which I think your wife will like as well. To be a legal Valentine's Day present it must be 1) a 'traditional' present, or 2) have something red. Rule 2 makes it
much easier to buy for a guy. The Seyco catalog has red print so obviously it counts.
Steve has a link to Seyco on the blog. The little vacuum
is a bit noisy but I just wear earmuffs over the headphones I'm listening to music through. A small amount of dust still escapes - there's always the bit on top of the wood - but it's pretty easily dealt with. The only way to have NO dust in the house is to have a separate workshop, and even then some will come in with you.
Make her a few nice things and she'll associate the smell with presents.
