No experience of that one personally. Looks very like the Moteck SG2100, but I beleive it's different. The pictures I just checked out on the net look odd to me in that it has the cable connectors on the top of the body (water ingress?). It's almost as if the picture is upside down, but I don't think it is, because of the logo.
It's a good and respected brand name in the 36V motor field.
By far the most common motors are the Motecks, probably followed by the more expensive STAB range.
Avoid the real cheap and nasty stuff. The excellent Moteck can be had for around £45 - £50 now.
