I recently built new wheels using Sapim Race DB spokes (2mm/ 1.8mm/ 2mm) that I purchased from Thor USA for $.55/ spoke which I considered extremely cheap.
Sapim Spokes and Nipples The rim are DT Swiss TK540, the front hub is a SON 28 dynamo hub and the rear is Shimano Deore LX cup and cone hub. Both are 36 holes. I think these are extremely strong wheels.
