Yep, Amazon has a nice selection of the Qi parts as well - plus the reviews on Amazon are pretty useful in most cases as well. O+ took themselves out of the running for my $$$ with those choices.
Depending which phone you get next, if they have Qi as an option, the naked coils with contact pads are available, and often can just be retrofitted into a stock cover or internally into a "sealed" phone. The receiver-plugged-into-it approach is just ughhhh. ;)
