I have a spindle speed control on my current cnc machine and I use it every time i run the machine. On a router you can also make speed control work e.g. with a product like this: http://www.vhipe.com/product-private/SuperPID-Tech-Info-Support-FAQ-Downloads.htm
I would hope there are some more economical solutions out there for routers.
I could be wrong, but I only recall 3 or 4 people using a spindle on their maslow in this forum.
for the $155 price for the super pid you mention one can buy a 500W brushless spindle with controller, power supply and z axis. so not really an economical product.
anyways not trying to be negative, any improvements in software are welcome.
The router we are using is already variable speed. I think it would be very
interesting to look at what could be done to control that speed electronically
rather than with the knob (this may also give us a wider speed range).
I now have 3 of these routers, I may open one up to take a look at this.

You can always build it yourself much more cost effectively: https://sites.google.com/site/klaasdc/cnc-router/spindle-controller
