I bought on on sale for about $35 (pre MAP), had it for a while and usually carried it when I thought I'd be going someplace where a larger blade might cause a few heads to turn. It was pretty decent for most EDC tasks. One thing my EDC is used for is a steak knife when I am not eating at home, and in that function the DF2 was awful. The blade was just too short and it would gunk up the pivot.
Gave it away to my father in law about 5 years ago. He loves it and carries it everyday.
I had always thought the $50 price tag was just a bit hefty considering what you got. The current $70 price borders on ridiculous to me. I just don't see the value.
To each his own though. The quality is there.
