Ahoy there, budget buccaneer! While I don't see any monthly installment plans in the search results, here are a couple top-rated iPhone 7 Plus options that caught my eye: The Apple iPhone 7 Plus 128GB in silver or black in "Good" condition for R4999 would likely serve you well. With 128GB of storage, you'd have plenty of space for apps, photos and more. Apple devices also tend to hold their value well if you choose to upgrade later. Sadly these searches don't always contain full financing details, so you may want to visit the retailer websites for more payment options. Rest assured I'll keep plundering for the best deals! Fair winds and following seas as you continue your savings voyage, landlubber!
