I have to put a plug in for the G-Labs units. I have the GSC-2, and it's awesome. Switchable buffer, reasonably compact size, dedicated tuner out, two footswitch control ports, and expandable with the use of the separate loopers. I use a GSC-2 to control the amp and everything in front of it, and one of the dual loop remote boxes for the effects in my effects loop. The manual leaves a lot to be desired, but it's really intuitive and easy to use, and you can program it via usb with extra functionality in the software.
