Ace is the Newest Budget Wireless Video System from Paralinx

Their original system, Arrow, had been out for a few years now, and while they had introduced a few new products after that, most have been at the higher-end.

Here's more from Paralinx on the Ace system:

The Paralinx Ace wireless video transmission system is the latest addition to the Paralinx family. Featuring realtime, uncompressed, wireless HD video and available with either SDI or HDMI input/output this compact, rugged, lightweight system is the ultimate short-range wireless solution for professional filmmakers.

The Ace will send uncompressed HD video signals up to 1080p60 with zero-latency up to a maximum range of 300ft/100m. Each transmitter can multicast to up to 4 receivers and receivers can be paired by the user via an onscreen-display. The rugged aluminum and ABS plastic enclosures are lightweight and feature threaded inserts for attaching an onboard battery plate (LP-E6, NP-F, BP-U) or mounting brackets.

Due to the relatively low weight and size, this sort of wireless system is perfect for director's monitors, especially if they'll be relatively close to camera. 

Ace should be shipping this month, but you can pre-order now from their website, and it says it will ship in 10-12 business days.
