I'm definitely happy to look at second hand. Thank you
You need to be careful. Every single cartridge for sale on eBay is low miles, not much use....yeah right. Don't get me wrong, I've bought and sold used cartridges but you need to be able to trust the seller or you could easily end up buying a totally worn out cart. With MM, I'd basically assume you're buying a body which will need a new stylus.
In the price range you're looking at I'd stick with MM. Cheap moving coils aren't made of magic, they're just different and you may not even like them more than a good MM. Plus, once they wear out you're replacing the whole thing rather than just the stylus. Unless you want to move into spending proper money on carts I'd stick with MM.
