I need to replace my alternator. (1988 V6 4Runner)

My original gave me 16 years of service.

I plan on installing a Warn winch that requires at least 60-70 amps. I also plan on installing a couple of nice off-road lights.
Should I go for another Toyota unit or should I try going aftermarket? I have had bad luck with rebuilt alternators. For some reason I have had to replace them a few times under warranty until I get a good one. The only aftermarket one I would probably trust is made by PowerMaster ($550), it supposedly puts out 175 amps at freeway speed and at least 50% more at idle.

How much could a stock alternator handle? How many amps does it put out?

Stock alternator is 60 amps.
