Just ask 440 Source on how good they balance ( did you get a balance sheet with it ?)
Why would you believe another shop that want to make money over 440 source that balances their own assys every day.
I see it here every day .
"I'm better than you and know more than you .
A second opinion shop would bad mouth the first just to get your $$$$$
My 2 cents. Not that it matters.
