I find my DSN will provide me with all the basic meters I want.
Today I was given the Accu-Chek Aviva expert after completing the local DAFNE course. So far the system has been great nice colour screen, lots of graphs to play about with. Finally got my ultimate geeky meter!! Once I had it setup it tells me my Bolus rates for each meal after counting the carbs. Not a cheap system mind you was told its about £120 to buy.
