If you're not adverse to carrying 15lbs extra, get a heavy chain and a U-lock combo. This provides as much security for your wheels as Pitlocks + a Ulock, and will cost you about $80 for both, instead of the $150 that you quoted.

It will also give you more versatility because the chain is able to lock around objects that a Ulock does not fit around. The downside is weight, but that should be 'ok' if you are mostly riding in flat terrain.
