When I was in the market for a sound level meter I did some research on same and finally ended up getting the RS one. Not because with was the best but I had very little choice. Yes the next upgrade from RS is way too expensive to justify the cost for which it was going to be used. RS meter does the job well without putting a dent on your wallet.
