Any 8 speed chain will work. Obviously the better chains have advantages the cheaper ones don't.
BUT, if you don't care about it being an 8 speed chain, use a 9 speed chain. I have been "one upping" chains for years. They work exceptionally well They last longer, are quieter, shift better and the cassettes last longer too. Even in mountain situations, one upping a chain works great.
So yes, you can use a 9 chain on an 8 drive system. 10 on 9, 11 on 10. But try and stick to better chains.
On a side note, KMC makes some of the Shimano chains. So if you get a KMC, yes, you are getting a quality chain. Taya, Yaban and Izumi all make excellent chains. As well as Wipperman. And the huge plus with a Wipperman....Stainless Steel! SO no rust.
Hope that helps.
