Definitely good prices, quality and performance if you have them close to the hub or have an XBee, Sylvania Smart+ (non-version A) outlet. Purportedly IKEA Trådfri bulbs. and Initial tests here seem to suggest that also the new IKEA Trådfri Outlet may be compatible repeaters, but statistics have not been obtained for those last two. Hang loose, we'll know very soon.
[Edit] IKEA Trådfri Outlets and Trådfri Repeaters are the best choice for low cost repeaters for Xiaomi
