Make sure to buy one with a dedicated button for each letter you want to use. Really, I would recommend something QWERTY just for standard compatibility.
Scarastic jokes over, it literally doesn't matter at all. Just look online for the cheapest keyboard with the features you want. Type on a cellphone touchscreen keyboard if you are so inclined. If you are typing so much that it really starts to hurt your finger joints or muscles, then you can maybe start to look at ergonomic keyboards and see if they'd be right for you. Beyond that, your time is better spent actually coding than worrying about the proper type of keyboard to use.
Counterpoint, the only way you'll be able to write efficient and clean code, that's both terse and readable, that earns the respect of influencers and CTOs alike, is with the Happy Hacking Keyboard, Type S. It's $300, but you're serious about coding, aren't you? And you'll need some after market keycaps; the stock ones are decent -- dye sub PBT -- but you'll look like a noob, you'll need to get a few sets of colorful blanks and create a pattern from them that defines your coding aesthetic. You have a color scheme that defines your coding aesthetic, right? If not, you need to take care of that, before you even write a single line of code.
