If you're limiting yourself to 32mm, no point in going with 29er rims, unless you find something cheaper than 700. Velocity and Sun/Ringle provide some decent options for a reasonable price.
I'm not sure I'd agree with this. Disc specific 29er rims are often lighter and the extra width does no harm.
