I love my Speed Queen Ultramate dryer...
It has 5 temperatures (Self-clean, incinerate, cremate, roast and pretend it's drying)
I love to simply skip the spin dryer and toss a giant load of towels spun in the ultra mate washer or the Marathon washer or the Kenmore Catalyst and it dries in a heartbeat.
No yellowing ever, but I've already incinerated and shrunk a synthetic king size duvet that turned into a doormat using the delicate (sic) temperature.
I'm looking forward to have the Marathon dryer hooked up, so I can incinerate two loads simultaneously.
Now truth be said.... Except for the duvet that turned into a doormat, I never had any issues with the SQ dryers. No yellowing, no shrinking... I just love that dryer and the way it can dry much faster.
And for delicate items, I have the magic chef, a Niagara and the 110v Skinny mini dryers, being Niagara my favorite because it's really gentle.
