We have considered building our own system, utilizing components such as purchased solenoids and build our controller, but being a small team (7-8 team members) and having only a little experience, means we cannot afford spending manhours on designing such a system.
No offense, but I am very unimpressed by this type of decision-making.

The time to properly decide on a purchased system is the same time, or less, that it takes to design your own. A pneumatic system is a very, very simple design exercise.

It is my opinion that purchasing a system is actually wasteful in terms of resources, and certainly does not promote any learning.
