SME arm on Technics is a bespoke modification. You will need engineering skills to perform this mod. GSA audio could perform this mod for instance but it is not exactly off the shelf.
Rega/origin live plate for mod is about £40.
Again I don't recomend these to you but just wanted to give all the facts.
Can't give you any other avdvice. I personally don't buy anything without hearing it/seeing what its made of and I pay no attention to reviews.
