I've been looking at the BAK bakflip cover and it looks promising but i just wanted to see what you all thought and if you have it, how it holds up.

I just got one for my 01. Took all of 10 minutes to put on and I love it. Have a pop lock on the tailgate so it's totally secure. the only drawback I can see is that it lowers your bed clearance, for boxes and stuff by about 2inches, as compared to fiberglass tonneaus, or the raised roll up kinds. I would recommend it to anyone. I was thinking of fiberglass, but since I often put the harley back there, this one folds up so neatly.
Hope this helps
