To be honest, my choice was governed by what I could get for free. I use the Accu-chek Aviva from Roche.
I like the carry case it comes with and the free software that anables me to print out some graphs.
It is a simple and straightforward meter that is fast to use, you can flag up particular results at the push of a button.
I also have a Bayer Contour from the "competition" here. It has a lot more features, when I got it, I'd started using the Aviva and had stocked up on strips. Enter the competition, you will get a meter, it isn't a real competition. The Drug companies are falling over themselves to give them away because the money is in the strips and lancets.
You will need to be persistent with the VAT, some staff, especially in the smaller pharmaices, just look blankly at you.
You can get strips cheaper on eBay. Check sellers out and make sure it has a good shelf life. Set yourself a limit and don't go over it. My limit is half the price you would pay at the shops (including postage), but I usually pay considerably less.
