No quite Eddie, you can get a Guru for not much more than the IQ120, but have to import it yourself.
Also none of them are water proof, but with the stoker and guru's you can keep them dry with a zip-lock bag where the fan isn't built into the main control unit.
Stoker does cost a bit more (mine cost £450 imported for a 2 fan system with some meat probes) but can be set up to automatically switch to a holding mode (drops to 180f) once the meat has hit it's target temp'.
Also environmental health loves Stoker log.
