Reply to Acapella Transitions - HELP!

Ok so I just discovered these acapella transition tools that dj's have used in battle routines and sets to spice up their performances....

I'm on two different record pools and I can't find! I need some ASAP and I do not really feel like taking the time to learn how to do my own in FL.

Are there any other DJ's here using these? If so, where I can get my hands on a few!? I'm specifically looking for a way to get from about 105 up to 128 bpm.

Thanks!
