I recently attended the WW Show in Baltimore and purchased a new Jet DC 1100CK dust collector from the local distributor. This is the new canister model. They only had 1 on display & convinced me to take a DC 1100A home with the promise they would ship the canister on Monday. Friday's UPS shipments come & NO canister. I called the distributor and was told none in stock, but Jet products arriving everyday. I was in Baltimore today and stopped by the store to inquire where was my canister. The sales rep told me that Jet has backordered the canisters until mid Feb. Now they have my money and I have half a dust collector. Yes I could use the 1100A, but the 30 micron bags are no better than the Grizzy I just sold. This great deal, where I saved about $40.00 off the normal retail price will cost me at least 7 weeks of aggravation. The moral of this tale is BEWARE buying machinery at WW Shows if you don't personally carry it home with you. Since it costs the vendors thousands of $$$$ for a booth they want to sell as much as possible even if they don't have it.
