I am one of those old dinosaurs that happens to agree with you. I would rather spend the extra 15 bucks and get the whole package. I would rather bring the wrong Tx to the field and not fly, than to take off with the wrong model selected (I've seen it happen too many times - as a matter of fact, just last weekend it happened to an expert flyer - resulting in one rekitted Dazzler), and with my brain... let's just say I KNOW it will happen.

Besides, even if you have a computer radio (which I do) you will still have a wealth of extra parts (Tx battery packs, switches, knobs, etc) if anything should need replacing.
