Hi I went to Leahuat and Seawalk since I lived in the East, personally I felt Seawalk is more honest and down to earth type shop. Leahuat seems to be trying on your technical background. Upon telling them I am a houseowner, the guy straight off tell me the stuffs are Japan made and no other shop have these. Charge me for $400 for something I could get in Jinyu for $50.
