LApolicegear had the Thunder Ranch Urban Rifle Illumination set on sale for around $85 this weekend. It includes the new "Shock-Proof" TL-3, green filter, rail mount with AR-15 handguard adapter, lanyard and pocket clip, and an instructional DVD by Clint Smith.
Given that normal TL-3's are running about $50, it seems very reasonable. I've been running a TL-3 LED on my "SPR Lite" for a while now, and am very happy with how it has held up. The new Streamlight mount has a clamp that mates with the grooves in the flashlight body to prevent movement. The Botach mount must be tightened very well to prevent slippage, so the new style should be an improvement, which will also allow dismounting the light without tools for handheld use.
I have 10(!) Streamlights (three TL-2 LED, two TL-3 LED, two TL-3 xenon, two 3AA tasklight, and a 3C twintask) and all have provided great service. One TL-3 xenon did have a defective spot weld on the lamp holder "out of the box", for which Streamlight promptly mailed me a replacement part. HTH.
