TN-730 vs TN-760: The high-yield TN-760 pays for itself before the first swap
The HL-L2460DW ships with a starter TN-730 that only gets you about 1,200 pages, so spring for the TN-760 (roughly 3,000 pages) as your first replacement. The cost-per-page difference is significant enough that the TN-760 pays for itself before you need to swap.
