REV Limiter on a 340

I was looking at the MDS soft touch rev limiter and was wondering if anyone has tried this system or any others. If you have please recomend one or any success stories will be appreciated. Thanks

I have no experience with the MSD limiter, as I currently run a Mallory ignition box with limiter built in and have had no problems with it. One downside of the MSD setup is the need for individual "pills" to keep track of and loose, thats where I prefer the digital readout of the Mallory box.
I have mine set conservatively at 6500rpm on my decently built 340.
