I have a Contour Next (not the USB one though) and the cut prices for the packs of 50 strips on eBay are generally double that of the Codefree strips. It really depends on how much you are happy/willing/can afford to pay for the strips though - it currently costs me around £70 odd a month .
If you meter is anything like mine you should be able to to do quite a lot of analyses of your readings on it: I can set targets, log several hundred individual readings, and view weekly, fortnightly, monthly and 3 monthly trends. But you can also register with Bayer and download their Glucofacts software for use on a PC. This will give all sorts of extra data and graphs and statistics as well from the uploads from your meter, which you can also print out, and you can download the readings in CVS format (and I think other formats too) for Excel, etc if needs be.
