That price is for 2 pedals and I have no idea how rare or not that Jen Phaser is. On average you can easily find a Roland AS-1 for $150, and if you're lucky something closer to $100 or less.
I remember reading a few reviews that complained that the as-1 added an unwanted distortion.
Also it not being in the gallery is intentional, it's not Boss. :)
Although I wish Boss Area would pickup the line of old Roland Pedals.
Yup, didn't look closely enough. But the case looks extremely similar to the BF-1 -- does this pedal predate it? Did they switch to the Boss name around this time?
