I have that exact one. It's a great deal. Everything came perfectly aligned. I didn't have to do a thing.

You will want to add an air assist, though. I ran a $50 compressor through the back and I just duct taped the tube right next to the laser pointer. It made a HUGE difference.

You will likely want to grab some transfer tape too. It makes everything nice a clean. I've tried a few. This is the best (and probably a lifetime supply.)

Love my OMTech, but I don't have experience with any other brand. It worked right out of the box. No alignment necessary. I am using it just for cutting. For that purpose, you absolutely need an air assist. I bought a $50 air pump off of Amazon and it works great. These are the last things that I cut. They are only 5" high, so that's some intricate detail that I didn't think I was going to be able to pull off.

Other than wood, the only thing I had to purchase was transfer tape (to keep the burn off). I tried a few and this is the one you want.
