My first scientific calculator (h.s. in the 80s) was the Sharp EL-506A. Came with a vinyl flip case. I wasn't fond of it because the buttons were too soft and didn't have much tactile feedback. In addition to the owner's manual it came with a book called "Conquering the Sciences."

Another one I had was the TI 36 Solar, also came with a vinyl flip case. The reservation I had about this one was since it was solar-only, memory wouldn't be retained when the light power was interrupted. Came with a user's guide called Texas Instruments Scientific TI-36 Solar Guidebook.

My old TI 36 Solar looked nothing like that. Just a black hunk of plastic. Wound up selling my TI-89 a few years back. Got what I paid for it back in 2003, so it served me well.
At some point I had a Casio, which I no longer have, but I still have the book that came with it called "Computing with the Scientific Calculator." This one and the Sharp one have some finance applications, though these are not financial calculators.
The last one I got, in college, was the HP 20S, which I still use today. This was their low-end, non-RPN calculator. All of the ones I used were reasonably well constructed, but the HP is built like a tank. It came with a printed owner's manual but not a separate applications guide.

I used to have this Radio Shack one ... might still have the box somewhere. I thought it was pretty fuckin' cool that the cover contained buttons, but it meant you couldn't (or shouldn't) fold it behind the calculator because of the flex circuit in the spine. My friend did that once, not knowing about the design and I freaked out. Lost it when someone stole my bag from the car.

Brainlets......
I didn't need to own a calculator until I was in college and I just bought whatever decently priced one I could find at walmart. Never really thought about the brands or whatever
