Hey Mr. D,
You can also do all sorts of modifications on standard weapons. I do it all the time, I have several examples of some of the modifications I have done on weapons in my brickshelf gallery look in the armies and the 3 different Character folders if you want to see them. Mostlya different style of axe, blunt weapons ect... If costs are a concern to you, modifying existing parts is a good way to diversify your weapons. I may do an article on part modification, would something like help?
After a long absence, I have returned. I can't wait to start building again.
