For a $125 machine, you have little to lose by trying off-brand toner cartridges. If the machine doesn't print well with the stuff, oh well, buy a different brand printer that will do ok on generic toner.
I do quite a bit of printing in my small business. At one time, about 1400 pages/week... but now closer to 600/week. For many years I favored the Okidata LED page printers, but they did not like generic toner. Lately I've migrated to Brother printers, and they do fine with most generic cartridges. My 5370 doesn't seem to like the "Premium Compatibles" brand, though, so I stay away from it. For that Brother machine I mostly buy Xerox cartridges from Provantage.com, and they're less than half the cost of OEM. I've been buying toner from Provantage for over 20 years, and their prices are consistently good.
I always try to buy a printer that takes at least 6,000 to 8,000 page toner cartridges, because it works out to be much less expensive that way.
