I just read this whole thread. I'm so glad Bently is doing better. What a harrowing experience! (As well as financially draining! ) Obviously, like many of us, you put your Bently first and worry about the $$ later. That is true love and a
good momma. You might want to look into some insurance. They don't pay for preexisting nor do they pay up front; it is reimbursement only, but reading all these threads on YT convinced me that $39/month (the one i went with) is worth it "just in case". If I never use it, great. The company made $$ off me. If I do, though, it's well worth the expense.
I hope Bentley continues to improve and returns to baseline. Keep the updates coming!
