Sucks to be the odd man out on the discount. With pulselites a customer requirement in the GOM I would image precision is capitalizing on that closed market.
But you have an alternative if your aircraft is N reg. You can purchase the same 250W unit ($383) I installed in a fixed wing and obtain your own Field Approval (Form 337) and install it in your helicopter.
Each pulselite kit comes with an STC and install documentation which can be used as approval basis data for Block 3 on the 337. The unit I installed from aircraft spruce had documentation showing install on a Robbie so that helps the cause.
A quick check online found 500W and 1000W kits for sale at $1100/$2000 respectively (links below). Same 337 install method above would apply.
Good luck.
