You are correct - there are 3 models. I originally wanted the TOL, but was told that they were on back order and when I really looked at the dryer most of the features that set it apart from the next one down were primarily for perma-press fabrics (none of which I own). They included an intermediate temperature, optional extended tumble, and a drying rack. I decided the MOL would be fine. The one that was delivered does not have an interior drum lamp (something I really wanted, and the MOL does have the light) and although it is a 'auto dry' model, not only does it not have an adjustable end-of-cycle signal, it has NO end of cycle signal (WTF?). There is nothing wrong with this dryer and if I had set out to purchase this one, it would be fine. But my sales receipt is for an ADG3LR dryer and what was delivered was an ADG30R. This is NOT a "new model", it has been in the line-up as long as I have researched SQ products, and this model does not "replace" the ADG3LR. I am highly insulted that the salesperson pulled what I consider 'bait-and-switch' tactics on me. If Castleberry's didn't have the model I wanted (and bought) then they should have explained that the only gas model they had in stock and could deliver yesterday was the BOL model. A second dealer that I talked with yesterday told me that SQ was having problems keeping up with demand and SQ appliances, at least her in Atlanta, were hard to find. If I have to order and wait for the one I want, I will do that. I intend to disconnect the SQ dryer and move my old MT back into the kitchen until the one I want can be delivered and installed - by anyone but Castleberry's.
