Some people prefer the PCBs' date=' some people think the parts are superior (though I've read they're not tested/matched as per $$$high end builders$$$), and some people like the mods available. General Guitar Gadgets has some great kit offerings, but BYOC has a few things that set it apart...or so I understand. It's only as good as the guy working the soldering iron after all. [/quote'] as far as I can tell the only thing that sets them apart, is that some of there kits are heavily moded and they cost alot more.
