I've been using the Leica e7100i for a little over a year now, and I like it because it's simple, accurate, and Bluetooth with their Disto Transfer software for Windows works well with the cabinet software I use (20-20, which does not work well most days). It's probably not that well suited for outdoor work. For $150 I am pretty happy with it, but if I had to make the purchase again today, I would at least check out the new Bosch LDMs and see if their software would be adequate.
Truly, the low-priced Leica is really easy to use, and so is the software. I opened the package, downloaded the software, paired the LDM with my laptop, and had it all set up in maybe ten minutes.
