Alright, so I'm looking at replacements and actually found a couple OEM replacements for slightly cheaper than aftermarket. With the way this thing just fell apart due to rotting, I'm inclined to go with the aftermarket version. I've read that in many aftermarket products, they work out flaws in the original OEM product that they're copying. I've found three different types.
OEM - ($29)
Aftermarket - Found This One on eBay, but there is no brand name mentioned, which worries me a bit. ($35) (Other sellers had them for $30, but from Hong Kong)
Aftermarket - Dorman brand - This is what is sold by all parts stores online. ($36)

Anyone have any input on this?
