Errr, the band is selected using internall straping resistors as you know, the internal LDO is also a component that is stuffed or not inside the modules housing. I do consider this to be different, at least for the average RC-Groups user. Depending on where you buy them, the price does not matter. I formyself also use the standard Band E modules, but stating here they are all the same could lead some beginner to try to combine i.e. a Band A module from RangeVideo with a standard Band E Rc305 leading to a tuff time for said beginner IMHO. It's all about not posting inadequate information. Not every reader here is electronics savey.
