I ran across the Pioneer with an Ultegra crank and chainring via Craigslist for super inexpensive. That's why I started the thread. RFLKT+ is nice, but still needs phone, so it's a silly purchase at this point in the game. I have the Elemnt, but as I said, when I'm on the back trails I'm listening to Podcasts. That means I'd have both the iPhone and Elemnt mounted, which is cumbersome to say the least. In the end, I'm returning the Elemnt in favor of Podcasts (iPhone). Someday, when I "need" a power meter, I'll be on the lookout for one with Bluetooth, because realistically ANT+ is probably dying sooner than later.
Thanks everybody for chiming in.
