First off, I am no expert. Now having said that, I would have to as about the ratings that you have espoused.
In the case of the original servo, is that continuous rating or max? Same question in the replacement ones. Also, what are the rpm ratings of each of these units?
I would suspect the originals are rated at continuous and the new ones at max (Thou shalt not exceed rating)!
For instance, I have in my box of "stuff" servos with rated speeds of say 1000 rpm to some with 6000 rpm ratings.
So before saying the supplier is on crack, make sure your comparing apples to apples and don't have a rotten banana in there:})
