I agree.
If some cheap bastard call's me and ask's "how much to change a head gasket?" I always give them a range - i.e. $500.00 thru $700.00. BECAUSE I HAVE NOT LOOKED AT IT.
My "labor guide" does not account for broken bolt's, and other incidental's, I EAT those.
If I was so inept, that I missed the water pump, and the valve job, then I would EAT that also. If your mechanic does different, maybe you need to reevaluate your mechanic.
Dish prefer's instead,to go with a "set price". for an install. Without even LOOKING at it.
I hope you understand,that you support the thought, that a small install, such as the OP's=a new receiver, XXX # of feet of coax, and a peek of the existing antenna, cost's the same as, a new antenna, a new LNB, a new switch, a hopper, a joey, etc, etc, etc.

Rob, the difference is that people bring their cars to you for a diagnosis. Would you go to their house, spend an hour doing a diagnosis on their vehicle, and then walk away with no pay if they decide to do something different?
The OP wanted a price on the phone for an unknown job. Here's the chat conversation if they did it the way you suggest.
CSR: Thank you for contacting Dish today OP, how may I help you?
OP: How much do you charge for running new cable from an existing dish to an owned receiver in my apartment?
CSR: Yes sir, I can help you with that. Give me a minute.
OP: Okay
CSR: Thank you for your patience. We can help you with this installation. How far is it between the dish and the receiver?
OP: Well, you'll need 38' of cable.
CSR: Thank you, we can do that for you. Give me a minute.
OP: Okay
CSR: That will cost you $74 sir. Are you sure you don't want a Hopper?
OP: No hopper, let's do the cable run though.
Two days later at OP's residence.
Dish Tech: Well, sir, I've run the cable and made all the necessary connections, that'll be $93.
OP: But the CSR told me $74.
Tech: You told her the run would require 38' of cable. I used just over 56'.
OP: But, there's no signal.
Tech: No sir, would you like me to fix that?
OP: Of course, I want to watch the ball game today.
Tech: Well, I can check to see if the dish is good, and if it is I can point it for you to get a peak signal.
OP: How much is that?
Tech: We get $26 for dish pointing.
OP: What if the dish is bad?
Tech: Sir, a new dish is $160 assembled and installed and peaked.
Etc. etc. etc.
