What are you going to use it for. In some cases, the red zebralight headlamp might be ideal. But if you need to throw red light a long distance, it won't work for you.
Given the price you mentioned the only one I can think of is the Proton Pro. No, I take that back. There is a LedLenser that has both, but I'd still go for the Pro.
The Photon Fusion also has a dual white/red beam setup similar to the Proton's for under $30, although it's more of a utility light than traditional flashlight. Between the two, the Proton Pro puts out much more light though.
1. Streamlight Packmate: 2x123 C4 (cree) led and 3mm red leds. side switch picks modes. Under 50.
2. Coleman Xponent 2x123 Cree with red leds. rotating ring/clicks picks hi/lo for red and white. Under 45.
Coleman makes one. About 90 lumens white,then a low red and blue. Runs on 3xaaa and I got mine for 20$. Forward clicky and uses a ring to change colors.
