Since everyone seems budget conscious here, I'm surprised no one mentioned kinlin builds from bikehubstore.com. That's what I have cause wabi was also out of stock when I was in the market. 1600g with a solid 28/32 spoke count. Cost was around 360$ including 160$ to get them built.

If I build up another bike based on an thick tubed alu aero track frame, I would consider Chinese carbon 38mm or 50mm wheels from yeoleo or something like that for under $500.
