Summit Racing Multispark street/strip CD ignition

if only i did a little more looking....here is a summit one with a two step as well as built in tach adapter to hook up my auto gage monster tach...seems like a wicked deal, and im tempted to give it a go...anyone have experience with these (or corresponding mallory peices)? should i upgrade my distributor to magnetic while im at it?
