The BT plasma is junk, I am a fellow CNC plasma user and I have looked at many of the plasma systems on the market and one glance at the BULLTEAR shows that it is a hobby machine built without any engineering behind it. This company is great for anyone who can not afford anything over $5,000 because it's not even worth the prices on the website. You have other options in CNC systems that will walk circles around that company. Heck even if you live locally to Bulltear you will find that ShopSabre is in the same state and they build a far more industrial spec machine for not much additional cost. I called both Bulltear and ShopSabre today just to price out the differences and you will see its pretty clear ShopSabre has an idea of what they are doing. Keep in mind the questions this guy has asked you to ask yourself are easy to answer about any machine.
1) if it doesnt have DTHC it is not a true CNC system
2) Resolution is not nearly as important in plasma check on Repeatability
3) Travel speeds will vary on the material your cutting and your torch, does not matter on what the machine is capable of if you can't get your cutter to cut a quality part at those speeds.
4) Anything listed as Proprietary is junk -- A Company should have enough money to give you a good quality Software that is built by a professional company. I would highly recommend considering a product by Enroute, ShopData, Radan. The motors should built by a top electronic company so you do not have a problem with burnign motors out. Easy way to check this stuff out is check the companies failure rates on the motors.
If you want quality ask yourself and the company you are consider these questions:
1) Does it use a cheap hobby controller such as Mach3? If so.. RUN AWAY
2) Does the machine use Linear Guide Rails with Linear Bearings? If not they probably use rollers or V-Guides which is over 10 years old... run away again.
3) Does the machine have a Steel Gantry? It should not have an aluminum gantry or bridge. Aluminum gets hot and causes problems with your squaring
4) Does the machine use a Machine Torch? If it does not require a Machine torch its junk... Hand torches are not designed for the cut quality and heat that a CNC plasma machine is capable of.
Sorry to burst anyones bubble hear but I was miss led by a CNC manufacturer on the market today (I wont say their name to save their face) but I ended up finding the answers to these questions the hard way... I highly recommend spending the extra money on a quality system. If the system is under $10,000 its probably junk and you won't want to show it off to your friends.
Hope this saves someone from being mislead by a manufacturer.
Good luck Everyone
