Timing Belt Suggestion please

Hi,

I'm going to replace timing belt, balance shaft belt and other related parts should be replaced at the same time.

Is OEM Belts the best? Or aftermakert belts (Napa or whatever) better than OEM? Currently I have Napa belt and haven't had any trouble for last 50,000miles in 4 years. (I din't meant to use Napa belt, but the dealer used napa belt, and i didn't know until a few days ago. I just found Napa logo on the belt!!)

What brand of timing belts are the best? I know machV sells super strong timing belt but it's way too expenssive.

Please give me your opinion.

I would go with OEM, or if not that the goodyear gatorback.

Use OE, if the dealer but a NAPA belt on my car (I wouldnt go to the dealer in the first place) I would snap and make them do it again for free, and put an OE belt on.
