Fair price for front disc brake conversion

Dr Diff kits are plug and play. Happy with my Dr Diff kit.
I did the conversion myself. Lots of painful issues with the brake lines as I replaced all lines with Inline tube products. If you are just converting to front disc it is fairly straightforward and easy.
Scarebird kits are good using Chevy cavilar calipers and Ford rotors, but not sure about what master cylinder is recommended.
With Dr Diff you get it all in one kit.
Before I tackled this myself I got some quotes that ran about $1500 labor plus the kit costs.
