The best thing to do is look at the different meters and decide which fits in best for you.
The OneTouch Ultrasmart has a lot of onboard features for recording meals, insulin intake, exercise etc. and is a bit like a very basic PDA. However, it is quite bulky.
Abbot's Freestyle meters are very small and compact but I personally found them too flimsy and inconsistant.
AccuChek's Mobile is brilliant (for me) because it doesn't use test-strips so you don't leave rubbish everywhere. However it's quite bulky and very noisy.
Have a look round and decide what you want. Even better, just ring all of them up and get a load sent to you. I've never had to wait more than 5 days for a meter company to send me a meter and it's good to get 5 or 6 different ones in front of you so you can find what works.
However, I'm forever disappointed by just how basic or fundamentally flawed every meter is. Some of them cost more than a budget mobile phone yet seem to be at least 15 years behind in terms of technology. How hard is it to make a meter with a backlit screen, a small light that comes on by where you need to put the blood, a lancing device that doesn't look like it's sized to prospect for oil in the desert, and keep it in something that's thin and fits in the palm of your hand? This really isn't too much to ask but meter companies seem incapable of actually designing meters for use in the real world.
