I have a Model 3 that a friend setup to run cartridge style needles with and it is a straight beast. With an adjustable aluminum grip and plunger setup for cartridges it still is lighter and more powerful than many of my pen style rotaries. If you want a coil machine that truly can do it all the Model 3 is hands down the lightest and most versatile coil machine I have ever used. I would highly recommend this machine and would say that it out performs many custom hand-built coil rigs costing 3 to 4 times as much. If you give it a try I'm willing to bet all your other coil machines will become trophies and relics of your beginnings as they probably won't see much run time. Couldn't be happier.
