Timing Belt replacement

Okay, I need to get my timing belt replaced, I have to have a shop do the work because I just can't take the time from work to do it myself.

I have been quoted $315 dollars for labor, if I use OEM parts it will be almost another 300 dollars.

I was thinking I should use a OEM timing belt but why spend $170 at the dealer for a new OEM water pump?

Does anyone have any recommendations? Should I stick with OEM or can I go aftermarket?

Thanks

I used aftermarket timimng belt and water pump from Checkers which is now Oreillys now. I am thinking it was Goodyear but not sure.
