front suspension options????????

i was wondering what are some good front suspension options for a 67 mustang. i do not want stock, im leaning twards the coil over kits so i can trim the shock towers.
fat man fabrication is one ive seen a lot of but i know there are some others that are good. what are the differences between the top 3 or 4 products?? i have done some research on the net but everyone says their suspension is the best.
