Yeah the lawsuit thing left a bad taste in people's mouth, including mine. But they make a solid product. Thing is, for me, Id rather have an XLR, MPA, Magpul Pro, or KRG. Even if bubble levels were never invented. Even if bubbles did not exist. The result for me would be the same.
Also, id like to second what Raining said. I actually prefer not to have a bubble in my chassis. It doesnt always line up right anyways. I prefer a level on my scope that I can true to my individual set up. Ive owned three MPA chassis. One level was totally true, another was very close, and one level was completely off. Id rather just not deal with built-in levels and have em' take 10 bucks off the total price.
