Newbrook, I just looked at Aquafina prices when picking up some things at the supermarket, and it was 95 cents per quart. I didn't see any distilled water there as cheap as $2/gallon. At these prices, it's pretty academic, though. And anyone who thinks his pricy ultra-pure water (my last bottle cost approx. $25 for 32 oz.) is going to STAY ultra-pure should read Wdi's comment.
On the broader subject, I find that the more steps I add to my cleaning regimen, the fewer records I can actually bring myself to clean. A second rinse would just about finish me off :-)
