@atl4love I'm not familiar with that turntable, so I'm not comfortable recommending it. It might be a great deal, I just don't know.
My experience with buying tables with used cartridges has been a bit hit and miss. I think you're better off buying a new cartridge.
You already have a nice turntable. I picked up a SL1200 recently and have been surprised at how good it is. I haven't tried my Hana SL on it, so can't comment on how good the combination will sound, but I would be surprised if it didn't sound great. I'm currently using an old Shure V15 Type IV with a Jico SAS stylus on mine and it sounds really nice.
I've heard good things about the Black Cube, but haven't heard one. The Parks Puffin is a nice phono pre and about half the price of the Black Cube. All of my other phono preamps are more expensive than the Puffin - I have a Manley Chinook, a Musical Surroundings Nova Phonomena, and a couple of Jolida JD9s and the Puffin can hold its own against them all.
