I can see dust being a problem with these from sitting at the distributors and retailers shelves for to long.
Maybe at the prices they are asking for them, they should be individually date of manufacture stamped (like a cars compliance plate) so when you purchase one, you know it not getting some dust collecting old stock that although it is not used it is really not new anymore and your not paying the retailer to help him out.
Has anybody noticed the economic times we live in. If they want our hard earned, then they have to come to the party or face extinction like any other business. The choice to purchase or not is with you the purchaser not the distributor or retailer that is what in the end will influence their pricing.
