Include the essentials
Add the purchase price, required adapters, delivery and the accessories you actually need. Keep optional upgrades separate so you can compare packages fairly.
Account for use
Enter your expected outing count to estimate cost per outing. Rental comparisons should include rental fees and the same length of use. Future resale values are assumptions, not guaranteed savings.
Check the terms
Warranty, returns, spare-part availability and servicing matter alongside cost. A calculated total is a budget, not a live offer.
