I don't have a Speed Queen model # because I have not yet bought one. They are more expensive than standard home washers but they are generally built solid. As 1 measure, they outweigh any other washer - shipping weight = 195 lbs. Stainless steel tub and galvanized steel box. I am looking at model AWN542 [top loading]. Our family does at least 10 loads of laundry a week and our Whirlpool is no longer spinning at all or agitating strongly after only 5 years. I don't know if this makes a difference in washer life span but the water is extremely hard where I live, Jerusalem; nobody needs any calcium supplements here!
