Suncoast is a good dealer and they do sell parts less expensively than most other dealers (except Sunset in OR). I've purchased from them a number of times and service is great. I'd definitely give them a shot at pricing the install reasonably. I hope you'll be pleasantly surprised by their quote. Know however they'll most likely not acknowledge the times I've given you above as dealers (I'm sure as a matter of S&P) reference the P repair manuals for time units suggested...
Let us know what you come up with and good luck
