I am a big fan of the Accu Chek Mobile if cost isn't important. It is very convenient because the test strips are contained inside the meter in a cassette. This means you don't have to handle the strips at all, so no contamination, and when the cassette is empty it just goes in household waste. It also comes with an Accu Chek Fastclix lancet pen. These are the best on the market and have a drum inside the pen with 6 lancets inside. This means you don't need to fiddle with the fiddly lancets that come with other devices. Once empty, the drums can also be disposed of in household waste. The downside is the cassettes are expensive.
