Scheu/Eurolab TT - which tonearm, mat

I am about to buy a Scheu/Eurolab PremierII turntable, probably with a 50mm-platter. I am undecided, however, about the tonearm-choice: Does it pay to go with one of the Scheu-arms (especially the Cantus or the new Tacco), or should I rather buy a used SME series IV or V? Anyone compared/switched? Another question for the flimsy wiring of the Scheu-arms: Anyone replaced them with sth else? And lastly: What is the best TT-mat for the Premier? Living Voice Mystic Mat, Ringmat, Extreme Phono-Non-Felt, or sth else. (I even thought about testing a blue leather mat made by Acoustic Solid, it does look so nice...)
