Since this is an older printer the toner cartridges from HP run 130 for just one!
This is a pretty normal price and it is a probably a new cartridge and not a refill. Many toner refillers only put more toner into a used cartridge even though many items wear over time like the photoconductor. Reconditioned toner cartridges I have no idea what that means. It probably means that key components to good print quality are not replaced like the photoconductors and developer rolls and charge rolls. Each of those components has a life and at the end of life of beyond the life is when you'll get poor print quality. They probably clean up the cartridge, refill it and run a few test prints. You might inquire as to what Reconditioning means.
On the other hand companies doing Remanufactured cartridges will attempt to replace these worn items and that will drive the cost up toward where the printer manufacturer's price is but your shot of having more reliable print quality goes up to but it still could be hit or miss. Unfortunately the best bet for print quality would be to buy the manufacturer's cartridge.
