I've got the original Teensy (AT90USB162). Aside from needing to get some digitally signed drivers so I could run it under Windows 7, it was very, very easy to flash.
I would hope the Teensy++ v2 is just as easy. It uses the same software that I used for mine, which is FLIP (you can get it off the ATMEL website).
