the only way I could ever afford a BMG is with a harbor safety or tactilite. although the tactilite looks to be better quality, I have no first-hand experience to compare one another, but it's also a grand more for a magazine fed. they are similar in ice if the safety harbor is mag-fed and the tactility is a single-shot. anyway, I hear pretty good reviews about both.
you also have ferret .50, which is price in the 2k range for a single shot. you may wanna walk over to ar15.com if you don't get much opinion about the upper conversions here, there are probably more folks running them there.
