That certainly looks like a solid SB and might be great for food, but I think it has at least two other drawbacks.
The other two drawback I see to that SB for soap is, unless I am missing something, is that the blending arm is not detachable and not long enough.
A detachable arm, is a very important feature for me. In fact, it is a requirement, both for use in cooking and for use with soapmaking. I have only ever owned SB's with a detachable arm and wouldn't even consider the non-detachable kind.
The length of the blending arm is also very important to me, again both for cooking and for soapmaking. I do have one SB with a short blending are, but I only use it when I travel because it's more compact and I don't make large batches of soap when I travel. But at home I like to be able to use the SB in deeper containers sometimes, and a short blending arm would make that difficult. For cooking, I tend to use a SB more with soups, and since I cook my soup in large pots, the longer arm is a must. Otherwise I'd not be able to reach the bottom of the pot, or the part holding the motor would have to be immersed in hot soup and that just isn't something I would feel safe or right about doing.
