Yes the power torque mowers are easily found and aren't worth much ,I haven't mostly been able to sell perfectly good serviced 2 stroke Victa mowers for many years here as it's just not worth fixing them to sell for $50. when you could sell the parts for $50. (stater and wheels)
I sold one mower about 5 months ago as it was too good to wreck and the guy payed but still hasn't picked it up.
These days people only want to pay $25. for a serviced Victa 2 stroke here and about $50 for a 4 stroke.
At least the super 24 will sell for a decent price still, as there isn't anything else like you mentioned like it for the price.
