Is there any price difference between FLIR`s 9 Hz cameras and the 30 Hz (NTSC) or 25 Hz (PAL) versions?

The price of the slow video (<9 fps) version Tau2 and Quark2 cameras is discounted by about 2.5-3.0% from the equivalent fast rate (25, 30 fps) version. FLIR Vue and FLIR Vue Pro pricing is the same whether the camera video rate is fast or slow.
