It sounds like you have found a great place. This sure can offer peace of mind. What might help with the pennysaving too, is pet insurance. http://petinsurance.com/.
They pay about 70%. At least that has been my experience. They don't cover pre-existing and parasitic type of illnesses, like ecuniculi, but ear infections, abscesses, colds, snuffles, gi stasis, these common things are covered.
It cost about 12 bucks a month, or less if you have multiple bunnies.
