I see. I thought you were talking about another maker. I'm sorry, I might have mistaken you for another member who ordered blasters off ebay. I should have checked out the links.
If Doopydoo is not shipping then we have a problem as many on here are dependent on them. I assume that you would prefer not to deal with them again, which I would understand. If you are in the US I would recommend hyperfirm as an alternative. A bit pricier, but light weight and near indestructible. You can see sales-threads in our for-sale forum from time to time, or talk to member "slavefive".
