Now that we've got a space lab on Mars, when are we sending one to Venus?

We've sent probes to the surface before so why not again?

Admittedly the surface temperatures of 872 °F, clouds of sulfuric acid and crushing 93 bar atmospheric pressure make it a little less hospitable than the red planet, but the challenge is what would make it fun.
