I've had a surprising amount of difficulty finding the answer to this question via traditional means (vendor website, store clerks, etc).
I recently moved into a house and I've been updating various things within it on my own. I'd like to replace this old Delta shower faucet handle:
with a handle of this style:
I have a feeling I need to buy more than just the new handle, but if so, what do I need to buy? A new mixer valve, perhaps?

When it comes to trim kits for mixer valves, the method of attaching them can differ a lot between manufactures. If you can get the model number of the mixer valve and/or trim kit (trim kit is the handle and escutcheon plate, usually sold together) you can go to the manufactures catalog and see if;
1) different handles are available for the trim kit or
2) select a different trim kit with the handle you like. Most mixer valves will work with various trim kits from the same manufacturer.
At most box stores, they only display complete kits, mixer and trim together, however a knowledgeable sales person will know how to use the manufacture's catalog to select different trim kits to work with your mixer.
