HL-2130 printer (non-duplex) is about 4yo and now needs its 6th or 7th toner cartridge. It maybe could do with a new drum.
Costs are: Brother - Toner $67 and drum $140 (1000 pgs and 12000 pages respectively) $207 total.
Compatible - Toner $32 and drum $44 (1000 pgs and 12000 pages respectively) $76 total.
New printer alternatives:
Brother HLL2375DW (Duplex, LAN, WiFi) $194 incl
Brother HLL2310D (Duplex, USB2.0) $138
Q: If I refurbish the 2130, are there any other components that might soon break?
BTW: I don't do a lot of printing. Mono Laser suits me for black and I have a couple of Canon MFCs for copying, scanning and color work.
