By the way, does anyone have any experience (good or bad) with those ionic air cleaners like the ones Sharper Image sells? I've thought about getting one or two for a while now, but I've always heard mixed results from third-party sources (and they're kinda pricey to buy one just to try it out). But with allergy season upon us, I'm willing to try just about anything. Plus, I'm curious if they reduce the amount of dust that settles on things, specifically electronics (which I believe attract dust the same way that these things supposedly work, because they ionize the air around them). Which is something else that worries me, do these things have any impact on signal fidelity? Do they generate interference if placed near TVs or speakers? Please comment if you've got any first-hand experience. Thanks.
