My suggestion is to shop elsewhere and supply your own balancer and maybe for ATI while doing it.
Shops hate people supplying parts because they don’t get the retail markup Vs what the customer can buy for.
If anyone works on my cars, I supply the parts, because chances are I can get it cheaper than they can.

I looked at an 07 (about 29,000 miles, summer of 21, that had the chirp and pronounced wobble. I got a quote from a nearby Chevrolet dealer of around $1,800 parts and labor - I passed on that one.

As for price, again the $1285 is in the range, but I would check with a couple of Corvette specialty shops & again....most important....be sure of which HB you will be getting.

I would use a shop that builds cars rather than a basic shop or a shop that restores cars. They are scared to think outside their little box

From the GT500 community typically you saw more IW failures if you watch trends.
ATi though is a bigger household name and proven racing record.

One thing to keep in mind is that if you supply your own balancer and it happens to be defective, the shop will not do the rework without charging labor again. Why should they? You supplied a defective part. Some of the aftermarket balancers require heating because they are a tighter interference fit. Make sure the shop has the oven to do this step. Replacement of the seal is a good idea also.

I had mine done about 2 years ago for $850, parts and labor. I live near Buyavette in Atlanta and they have a very good shop.
I would look for a shop that works on a lot of Corvettes. Prices have gone up on everything so maybe $1285 is the correct number now,
but I would check more than a couple of shops.

The manufacturer instructs on proper install as well.
I have never heard of them needing to be heated. ATI recommends they be pressed on and not beaten also a sequence for bolt torquing to ensure it is seated properly and stays seated

I am surprised on this site that people suggest to only bring your car to a Corvette shop or a chevy dealer. If the shop tells you it will cost more just because it is a Corvette I would move on. Maybe I am just lucky to deal with a shop that understands the small block motor does not know the difference if it is in a Corvette or not..... It is just a chevy small block motor.

The balancer I purchased about 3 months ago from Summit was a SUM-C2501. ($199.xx)The instructions for installation were to heat the balancer at a temperature of 250 degrees for 15 minutes and immediately install. (I think I am remembering this accurately) I assumed that this was to slightly increase the bore size to make installation easier and reduce the possibility of stripping the threads in the crankshaft while pulling the balancer on. Summit didn't say this was optional, they just said do it. This could be done in a toaster oven but the shop has to have one. Dealerships don't. I wonder if the center hole in the Summit part is just a little smaller than the OEM part to get a tighter fit and avoid any slippage during operation later on since there is no key used.
