That's a little high, but about right. I'd say $1500 to $1800 is what I think of as typical. In addition to shopping around, I'd get them to identify exactly (brand, part number, etc.) what the parts are, so that you can ask them to price match on parts and figure out exactly what's being charged in labor. For a well done job with good parts, I wouldn't think somebody was crazy for paying $1750.
