I personally would go LayLax over PDI. The parts are easier to find, but they are both great brands. The thing I don't like about PDI is that they make some of their parts fitment different so that you have to buy more parts for them to work. If you know what you need though, it shouldn't be a problem.

You could go with the metal version of the stock trigger box; I've heard they are actually pretty strong.
