Has anyone tried this one?

Not this one. I tried Super Nano Pro 6 for two weeks, and didn't quite like how it feels. I like the paint job, but the different feel seems a result of missing some feature in more expensive Super Nano (1 & 3). I end up getting Super Nano 1, which cost more in US, but I got mine from Taiwan cheaper than Super Nano 6 or 7 in US.

YMMV. Try it if you can.

i see...i'd like to try the pro 7... the the price indicates 170$ CAD all included, i wonder if i can get it cheaper..
