yeah there a tad expensive. but i like the look they give a project, also note that you will find them in any high grade electrical equipment such as medical, military, etc.. they have a very professional look. However I'm not saying a project is better then another because they use dale, please don't take it that way. i do prototype with regular 3 and 4 band resistors but my finished boards get the dales. also now that i think of it, iv never blown a dale...
