Thanks for the recommendation of the Ctek 7002.It has a full range of accessories and responsive on-line tech support . In theory it has superior technology to most of the competitors -like Noco mentioned below.
The Ctek Multi US 4.3 seems to be the latest upgrade from the older 7002? The 'Bundle' seems to be the smart choice? 56-CTEKTOOLBOX-EXT for around $85.
