Well, hold on now, just because none of us have heard of it, doesn't mean it isn't good for what you want to do with it. From the website, it looks OK.
Plus I looked up the price of AutoCAD LT and it's about the same!
But if you've tried and tried and you're done with Bobcad, then, yeah, at least with AutoCAD it might be easier to get help from others.
Are you a student in CA?, if so, I know where you can get nice Autodesk discounts.
