I was just about to order the diy ss kit as well...but i found this site
www.pdamotion.com GM are partnership with this company...so they say the quailty is top notch like GM hard mods... i placed my order in almost a month ago and still waiting...they said they sent it on the 23Nov ..now i have to wait 3 weeks for it to get into Australia

hope its worth the wait..btw its the same price like the diy kit, and you get a free case and bag with it. checkout brighthand.com they are doing a special deal with them were ya also get a usb sync cable with it
