I had A Zeta on my LP12, and was bought from new. IIRC it cost about £900, and I ran it with a Mission 773 LC, Supex 900s, and various Linn cartridges. It was certainly a very powerful arm with oodles of bass. So £45 is a bit of a bargain! As has been said, check the bearings and wiring....both have had issues in the past. If it's in good nick, put it on an LP12 and it will sing again. Great combination. A word of caution....the arm is quite heavy so make sure the TT is set up properly, otherwise it will sound dull and slow!
