YUP I run two and have just ordered my third today!!!
I have work coming out of my ears but am just managing to keep up..... Just!! lol
In order to be seen as a reliable and efficient business it's better to have a little spare capacity than run round like a Blue *rsed fly.
If I dont have enough to keep the 3 going when I get the 3rd ( A couple of months) on the road I will GO GET however much I need.
