06 F-150 Remote Start By-pass Module

Which bypass to use on 06 f-150 i know there is the 556s by DEI or the PKF3 What is the prices on each exactly? i havent actually seen the pkf3, i heard it from a friend that said it should work. im familiar with DEI, but the 556s is hugemougous! is the PKF3 any smaller? If there is any smaller & cheaper bypass out there, please tell me Thanks

MSRP $75.00      PKF-3 - Ford Encrypted Transponder (PATS) Interface Kit     In Stock i dont want my bypass to cost more than the alarm itself. that seems kinda dumb

is there another place where i can possible find the pkf-3 for around $30?

I tried looking at that website, but i didnt know how to purchase an item or even look at pricing. I just bought a 556s on ebay for $50 anyways Thanks for the input though

The 556S is nothing but a 556U with a blank Ford key already mounted inside. It might have been cheaper to get a 556U or other similar bypass module, and buy a blank aftermarket key from a local locksmith. But for retail, $50 isn't too bad.
