Door window seals

[Ignignot]

Just replaced my drivers door window trim piece. Seeing how well the new one seals,) compared to the others, it looks like i should do all the others soon. Have any guys had luck with an aftermarket brand or should i cough up the $400 and go OEM?

Bought OEM from a japanese seller on ebay. All 6 pieces totaled $340 after tax and shipping

Anyone know where i can get a teeny tiny replacement snap clip to hold the door seal to the window seal on the front of the back doors?
