Rev-N-ator ignition boxes?

I Am really interested in the rev-n-ator module, i just wanna find out what kind of warranty it has, and i never knew they recomend no vaccum advance with the rev-n-ator box... That sounds pretty strange to me... and if thats the case i wont be buying one, i run my vaccum advance off of manifold vaccum, i have it set to add 10 degrees of timing at idle. I run 14 degrees initial timing plus another 10 degrees from vaccum advance for a total of 24 degrees of timing at an idle and my total timing is set at 32 degrees.
Don's ignition box from fbo systems deffanatly has the best warranty with a 2 year warranty, i have just read about so many people having trouble with his box that i am leary of purchasing it, i'm sure my ignition coil could handle don's box good because the coil i run is a crane cams lx91 e-core style coil that can be used with cd ignitions or inductive ignitions, don claims his coil is the only coil that can handle his box, but i bet my crane cams lx91 would handle it ok seems how it can handle a crane cams hi-6 cd ignition just fine.
I just wanna get an ignition that has a little more fire to it, wether it be a crane cams hi-6 cd ignition or a rev-n-ator or don's ignition box from fbo systems, but i also dont wanna be swapping out boxes and burning modules and coils up all the time, so i want something thats good and reliable. and it would also be nice to be able to get something that will plug right into my exsisting ignition harness. thats why i been mainly looking at the rev-n-ator and don's ar688 box whatever he calls it.
