Just to report back on this, I went ahead and picked up EasyCare TotalCare (3 yrs, 85k miles, $500 deduct) for ~$2600 for some peace of mind and a hedge against any huge bill in the next few years.
Hope to get my money back by the end of it, but if not, I'll sleep better in the meantime and be happy my car's been reliable. If/when I have to make a claim, I'll let you all know how it goes.
