I do not like the Martz unit, search the forum and you will not find much good about them. DSE, 21st century, Chris Alston, and now Art Morrison make nice sturdy subframes. I am not sure anymore which I would choose now. As for modding you original frame, you can really improve the factory frame enough to please most mear mortals, but it may not have the bling factor.
Also, if you are on a budget I have a used low mileage Chris Alston subframe for sale for $3500 with brakes.
