I've got a couple of P-Touch machines, a 1000 and an older 1250.
The fonts aren't as good as on the older Kroy machines I used to use (a little bit blocky) but they do work well.
The built-in tape cutter wears out after a few years heavy use, but that's no great hardship because...
You can adjust the excess tape setting in the menu. On max it's good for printing a single label, but if you're doing a lot of small ones like "DB1-6" for sockets etc, set it to zero, print them one after the other. For the final one you need to use the FEED function to spit out that bit of excess tape, otherwise you will cut your last label in half! Then chop each one off the length of tape with your sidecutters as you need to use it.
Battery life isn't bad, but they all take the Model G mains adapter (7V 1.2A unregulated). BE WARNED: The polarity is opposite to what everything else uses - it's centre pin negative!
