Welcome to the Router Forums Mike.
The HD series Sharks are limited to the smaller 1.5kw spindles because of the added weight, that is the size of the spindle Next Wave Automation offers. Theirs comes fully wired and ready to go but you can buy one and wire it yourself if you think you are capable of doing it and save about half the cost. I am using a Bosch 1617 on my Shark HD1 and it does a great job. The important thing to remember is you don't need to run your router at full speed. It will last a lot longer if you limit the speed of your spindle and adjust your feeds to the limits your machine will handle. I'm running mine around 16000 RPMs.
