Especially considering all the extra stuff you have to buy (chassis stiffening kit and transmission-specific crossmember).
I was watching Junkerup on Youtube, and in his latest video, he was doing a walk through on a car he is building for someone, and showed a very clean way to do the trans mount with a Gen 3 swap. It's in a Charger (B-body, right?) but I think the idea would work the same.
For those kind of prices, you could probably have it made locally cheaper.
