I also use Freestyle Mini which I'm happy with. Prevously had several varieties of Acuchek, the last being Aviva (I think), the one that comes with the Multiclix lancing device (6 lancets in sealed drum). Freestyle was provided by diabetes nurses, the others were free upgrades. Aviva was OK but rather big in its case, so when I started DAFNE and started eating out more, something smaller was essential to remove my excuse for leaving it at home. Ditched the Freestyle lancing device though, Multiclix is much better - just twist it for a new lancet each time when out and about, no need to fiddle with lancets, or remember which ones have been used. Spare or used lancet drums can be carried in a pocket/put in the bin because the sharp bits are inaccessible.
Convenience, size (the whole kit, not just the meter), accuracy and speed are the most important factors. Choice of colour or changeable covers (like on mobile phones) would be a bonus!
As already suggested, separate averages for pre-/post-meal readings would be good but I'd settle for this in separate software (more convenient in meter but not really essential on the move) and it needs to be suited to flexible regimes. For example the FreestyleMini PC programme couldn't cope with tests at 1pm being pre-meal one day but post-meal the next and its calculations ignored bedtime/overnight readings.
