I'm certainly open to other suggestions, absolute max budget is $1,500.

I like the width of those Reynolds, ideally you'll have a rim that's slightly wider than your tire for improve aerodynamics. So far this is only reasonably lightweight wheel I've found that offers a decent internal width and external width.
