Suggestions-New Ignition Set Up

This last weekend, while waiting in tech line out at the track, my MSD 6AL gave out. I want to use this opportunity to switch to a different setup. The distributor I had was barrowed, so the price of a new one of those and another 6AL is way more then I want to spend right now. What are your suggestions? It has to have mechanical advance and the ignition box has to have the potential to pull timming under boost.


Thanks
Jake
