StockMarketTicker.com is available and on-sale due to its owner retiring soon. In fact, a desire for retirement income is a reason the owner can do an interest-free monthly payment plan (and a buyer's benefit).
P.S. No worries about using the domain while paying. You will have the same use as if you paid purchase price up-front, and be able to use your own DNS immediately upon making your first payment.
