I cant help with your direct query unfortunately, but I do know that the Giottos anti-burn steam wand and the no-burn hot water wand designs are Patent Pending and I didnt find any other machine that has this feature. After burning my thumb and index finger good and proper on my sisters Saeco machine last year, this feature was the sealer in my decision to buy a Giotto over a VBM (see my other post).
Maybe you can get replacement Giotto wands and back-fit them to your VBM, assuming the bends and fittings allow the transplant? Chris at Talk Coffee sells and services both machines, Im sure hell have some ideas.
By the way, Im curious as to why you moved from a Giotto to the VBM???
