Not to my knowledge, I haven't recieved any 6100 pumps in a few weeks. The problem is the same the world over, I have been promised a fair alottment of pumps in the next few weeks and my advise would be to place an order and your order will be filled in the order it was recieved. I know all vendors have a backorder list on thes pumps. I would expect it could take as long as 6 weeks to catch up. It wouldn't hurt to call around but I know from talking with my vendors and with Tunze this is a global situation and we are still trying to catch up from Christmas.
