A good custom keyboard kit is built like a tank and should easily last you a decade. You are paying for heavy aluminum casing, hotswap circuit boards, and smooth mechanics so you buy once instead of replacing flimsy prebuilts every two years. Keep an eye on group buys and revision cycles. A board from last year's run or a previous revision often drops in price right when the new version launches, giving you high build quality for much less.
If you want to grab a $300 kit without taking a big hit to your bank account all at once, you can stretch out the payment. Financing it at zero interest keeps your cash in your pocket while you build.
This 0% intro rate is a strict deadline, not free money. If you still have a balance on your Citi Simplicity® Credit Card after 18 months, regular interest kicks in on whatever is left, so stick to the $16.67 monthly plan to wipe it out completely on time.
