I like them a lot, although the game tables I play on generally don't have much blocking terrain, to it is kinda a buzz kill for me. But being able to crack a GK Land Raider on turn one of a spearhead mission always puts a smile on my face. Sadly, I don't have that many T-T

I agree with LukeValatine, it's best to run them in small groups with meltas, that gives you a quick tank killer for just 150 points.
