The matrix is the new lance - 350hp 213 KTAS Cruise. You really are looking at an IR course to get the best out of this machine - at lease an IMC for UK use. The mirage is the pressurized sister - again for higher flight levels, but another system for you to manage.
Plenty of room for a 4 man raft and luggage, club seats and even an emergency chemical loo if you wanted - or a squatiing area for a shewee

I am a bit out of the prices these days, but the one I used to fly 5 years ago was close to £280 per hour, but the guy who owned it said that it cost him £400 as it never flew. For that you could fly a Seneca and give your family extra safety - they are slower though, but it is nice to hear 2 doinks purring away.

£290 from here but if you were in a group, you would get the aircraft you wanted - worth it if you are doing 50 hrs per year. Some groups give you access to singles too on the fleet.
AVOID the twin star *** and read the accident reports on the type that you are flying. This can help you from making the same mistakes.
