I have owned a CZ550 in .308 and also owned a previous model BRNO 601 in .308W. I currently own a .416 Rigby CZ Safari Classic (the base version, as sold here in OZ).

I have been very happy with my CZ 550's. My .416 was bedded perfectly from the factory and only needed the standard trigger adjusted (which took less than 5 minutes) and a larger front sight insert installed (easily done by the owner). IMO the CZ is an excellent start point for any DG rifle and they have most of the features found in high end custom DG rifles. They all need adjustment for individual use however. Any problems are easily and cheaply fixed or modified.

I would not pay $3K for a start rifle unless you need an exotic calibre. If you can afford the ammo and/or reloading gear for an 'exotic' calibre then you can afford a new barrel on an entry level CZ rifle or a bit of custom gunsmithing like a re-chamber.

As you are in the USA have a look at these guys who do a good job of modifying standard CZ's. They are familiar with the rifles and know what to look for and how to improve them.

Your friend may not wish to buy one of their whole packages which are overpriced, however a bit of bargaining may work and their web site may give some ideas.

There are a few posts here on CZ's. Do a search.
