I would just like to make people aware of this. I hired this gauge


from Greg and I must say it worked great. I was looking at a whole
new group handle and when I seen this, it was the answer I was
looking for. If anyone would like to know the pressure at their group
head, and not spend a lot of money, I would suggest using this device.
I live in Adelaide and Greg was more than helpful. I just thought I
would post some positive feed back on a great alternative to a more
expensive porta filter with a gauge.
