For sleeping bags you might find some deals on synthetic stuff but nothing will be able to perform as well as the SP1 you're referring to. Also when buying down I'd at least check out who's producing the stuff. There's lots of info in the sleeping bag thread

I've got an Aegismax sleeping bag. I dunno about the STS SP1 but I went bikepacking last week in Spain and it worked like a charm.
