On Island Pearl II we like the old B&G instruments but we have linked these to two new Raymarine E70 chart plotters (Nav station & rear cabin) plus a new ES97 at the helm. We went with a Raymarine 650 AIS, a Raymarine Network system to network all displays off any one of the plotters chart cards and added a 2nd full new Raymarine Autopilot at the helm with quick change over switch between autopilot 1 and 2.
These are all great but you could do the same with any brand, we just happen to prefer Raymarine now as it is robust (like B&G used to be before being bought out).
By far the best new equipment we added was the latest Raymarine Quantum radar. This little unit is absolutely incredible in picking up even isolated unlit thin mooring poles when night sailing and best of all uses almost nil power!! We now have it on all the time whilst sailing, and for the first time ever we now have peace of mind sailing on pitch black nights with no moonlight! It was not all that expensive either, and we kept the old Amel supplied radar as well as backup and for seeing further but haven't even switched the old one on once since getting the Quantum. Just moved it's screen back in the nav station area so we can fit a monitor in front of it on a swing arm to access the old radar when/if required. Also on the 2nd radar mount (1 meter below the original) we have a fwd and rear facing camera linked to the TV's so can see what's coming and going whilst sailing solo and down making a cup of tea etc..
Lastly, if it is not yet done, have the old B&G instruments linked to your auto-pilots and network. This way everything talks to each other via NMEA. We also have 4 extra Raymarine i 70 displays on the boat so we can see wind, radar, AIS, Speed, Depth on these too, plus to get the benefit of using the new autopilot on "wind pilot" mode which we sometimes find handy. Possibly all the I70's was overkill though and not necessary as we generally only have 2 of these on most of the time.
But of everything I would say absolutely the Quantum Radar was the very best buy.
