[TriLUG] Where to buy printer toner cartridges?

[Peter Neilson]

My Brother HL-3075CW works well on Ubuntu Linux, although it seems quite  
slow. But speed's not my problem today.

I've been buying replacement TN-210 cartridges for it at an office-supply  
store, for full price. Online I see a myriad of offers, everything from  
refill kits and remanufactured, to Genuine Brother ones, at an astounding  
variety of prices.

I do understand that the economics of computer printers follows the  
principle originated by King Gillette for his Safety Razor: "Give 'em the  
razor, sell 'em the blades."

Any recommendations?

Which online sites or local outfits are the Right Place To Go? Why?

Which are losers, not worth the trouble, incompetent, or just total  
ripoffs?
