I got mine from Eastern Performance Cycle on sale at 80 bucks off the normal price a few months back. That brought it down to 270 or 280.. can't remember
looks like various sights are selling them for 399 now.. for that price I'd just get the Power Vision and not have it married to one bike.
I got my FP3 off of Ebay for $284.99 in July, 2015. I would say anything above that is probably too much, lots of deals to be had on a product that has worked flawlessly for me. Good luck.
