YMark & Henry -
Sorry you've had bad experiences with other theme builders, but I know they would not have been with my themes, so the old adage that "1 person ruins it for all" is true
.
I have multiple BB's that all themes are tested on first. I just picked up a Storm yesterday so I can test builds for it.
On a side note, the Storm is a pretty cool BB. I originally bought it just for testing, but I can actually see myself carrying it on the weekends! The screen clarity is amazing.
