It all depends on what you want to accomplish with them. In many applications, it is possible for the rotational motion of a servo to be turned into linear motion. A prime example of this would be the pistons on a
steam locomotive or an
internal combustion engine. Ideas like this may work in some situations, but not in others. As with most things in life, there is no golden answer to which is better. Everything depends on what you want to accomplish how you design / build it. $230 may seem like a lot of money initially, but if you plan on using the pneumatics kit a lot, then it's a really good deal.
