I have a 4050DTN for regular B&W and a 5000TN for anything wide format. These two are absolutely bulletproof, I can get cartridges for my 4050 that can do 20,000 sheets at 5% coverage; a single cartridge got me through two degrees with zero problems. Currently on my third cartridge in almost a quarter century.
Will look into your M254DW as a colour option, per your experience with it.
