Power 8 and similar systems like the impressive 'Shop smith' are excellent providing you are good at planning ahead, as once you remove the so and so tool, it will lose the accurate cut/drill/routing set up meaning that if you forgot you needed to do more of the same or break a part then you have to set it up again and regain that accuracy or the new/extra bits will not be the same.
A band saw is very versatile and I have found that a quarter inch deep 14tpi blade is the most versatile, being able to cut metal as well as wood and plastics.
Do be mindful also, that a size/make of tool can go out of production and so the stock of spares may become scarce. The lower blade guid holder on mine broke and Axminster sent me the very last one they had. There looked to be a slight imperfection in the metal causing it to fail but the saw was no longer in warranty.
Enjoy the machine and look after it as it will save you time and improve accuracy.
