It is VERY easy to make a poll. When you make a new thread in a section (please make sure it's in the right section), write up your piece, then scroll down below the part where you type. Eventually, you'll see a little box next to "Post a poll" and it allows you to enter up to 10 choices. That being said, you may have to make 3 threads - one for "Favorite Machine For Lining", "Favorite Machine For Shading" etc. The only bad part, is that what machine to use for what, and how it's set up can vary so greatly. I know people who swear by a slow running Rotaryworks for colorpacking, and others who claim that at 2.7v, it is hands down their favorite lining machine. Sure, a poll can give you a thread overview at a glance, but many people may end up listing different machines than what you have listed.

Just food for thought.
