dude my pro 4 is da bomb! it seems like it is hard to get hoocked up at first and you might need to get rid of the one-way but when it is working it is working, i had the xray before i had the pro 4 and before i ran shumacher and i didnt really enjoy it, i couldnt get it set -up or it would break i would go with pro 4!!! if you want the good stuff...
