The Epson, Samsung, NEC laser printers are nice and work well BUT their life cycle for those products is shorter and the companies will likely not support them and or be able to service them later on through their limited dealer or service network. I have a NEC 870 and a Epson 1000 laser and parts are hard to find for both.
This is compared to a Xerox or an HP unit which costs more up front. The advantage is that there are more places that can service them and have access to more replacment toner and parts suppliers as they age when the fuser, rollers, imaging units start to burn out. Plus, feeding them is cheaper since you can get refurbished cartridges for cheap if you print in volumes and you can punch a hole in the cartridge once the toner is used (which goes for all laser cartridges) and fill them up, empty out the waste toner compartment and reuse them. For black only, that works, color is a different story. Remember to not expose the transfer roller on the toner cartridge to sunlight since they are sensitive otherwise you'll get some weird prints.
My 2 cents.
