Speed Tech or Art Morrison, DSE 69 Camaro Frame

[snappytravis]

I have been doing a little research on the subframes, I have also looked at the full frames available, Would like a little advice on What is working good, I know DSE is a superior product not to sure how long Speed Tech has been around? and AME what are the pros and cons of both products I don't want something that is going to be a nightmare installation and realize that there will be labor involved Like the c6 vette stuff from AME, seems that it would be easier to repair if parts needed, but may be wrong, Speed Tech looks that they are pretty much order from them if you need parts, I would like to get something ordered before end of year If anyone has used or installed these products let me know what you think thanks for your time.
