I was looking for a wireless mic system for my a6400 and found this as the cheapest & good option. Wireless1 is an authorised dealer listed in Rode's site. Therefore, you can register this product for free extended warranty (2 years). Good luck.
Don't forget Shopback 1%.
If you don't mind driving to Auburn and need this by tomorrow, then look at PCByte
Nice, been looking for a cheap set of these, thanks op.
Worth noting postage free over $200 too.
