Cheap window regulator f150 04
 

I just had my first incounter with a broken window regulator.. I see hundreds of complaints online..
I read that the part number has changed 3 times on the OEM regulator (may have been an old post).. post said ford only changes a part number if there is a change to the part.

I see there are a few aftermarket regulators being make,, problem is they are all for the front.. I could not find any for the rear.
I need a driver side rear..
Can anyone point me toward the cheapest price for one?
I found one for $140 shipped on ebay.. is this as good as it is going to get?

Thanks for any help.
