How do you guys feel about them? Because I have to say they're pretty damn cheap in terms of playing. Horn blowers have the ability to boost your entire army's courage up by 1. Every single model, so long as one horn blower is alive on the field. And I'm guessing that if you have more than 1 it is not accumulative.
The thing is that my friend, whom I meet up with every once and a while for a game, is quite content in having his horn blower tucked away in an isolated corner behind cover never moving him once. Smart, but that's what I find cheap about it. It would be great if horn blowers were given a range of 12" or something, but not even. No range is given at all. We could have a house rule but my friend wouldn't be so open to that since he has a horn blower and I don't.
In any case horn blowers are much worth the 20 points to boost your entire army's courage up by 1. To me that makes a difference when it comes to taking courage tests. So I guess the models are well worth the $$$ or time to convert a model if you're using one for SBG.
