i was looking into this and from what iv seen theres two to choose from , Aimtop svd and WE acevd , in comprison the WE looks better built and has what looks like a better quality finish on the body and is more expensive , I think the first batch of aimtop svds had weaker internals which might not be an issue now? both aim and we seem to have spares available , as for the best? i cannot answer that ,but idd probably go with WE .
