One, if you're using it commercially, it's going to pay for itself pretty quickly. I rarely do client projects for less than several thousand pounds; I reckon I could probably churn a lot of them out using this in half the time.
Two if you're not using it commercially, it's still a very low cost; maybe more than pure hosting but it does a lot more than just hosting.
I’m always upfront about the tools I use with my clients as the value isn’t in the tool, it’s in their requirements.
But being able to move away quickly is important to me because I have client relationships (and production code) that is 9 years old.
(I also don’t consider myself a contractor, more a consultant - a semantic difference but an important one)
Our consulting rates are way above that per week.
