How does you machine shop pricings compare from area to area?

last SBC heads i took to local (only) shop milled/valve grind and new stock springs was $400 bucks. (thats why I usually don't do any machine work).

Checked with a popular machine shop about 40 miles away and here is there prices.

Clean V8 block bore and hone 1 time $120 if it needs a second bore $150.

Clean, check and polish crank $18.

Clean, check and mill/grind valves and port out the area directly under the valves $155.

Thought those where some pretty good prices, what does yours run?
