Mrs WB627 ran a Beaver Colony for scouts, taught a Sunday school class at church and did a few other voluntary things on top of that that all required a lot of mainly B&W printing. Having gone through a couple of cheap laser printers which didn't last long despite refiling the toners, I bought a top of the range HP2300 DTN with a very low print count (sub 10K), on eBay for £40 with a nearly full toner cartridge. It was the best thing I ever did. We had HP2300's at work and they did 0000's of copies every week and were bulletproof. We've had it for 10 years and I'm only on my second new cartridge; I've only ever paid a maximum of £15 for a replacement (genuine HP toner) on eBay. The cartridge has the drum built into it so every time you put a new one in, you get a new drum.
Ha Ha
I bought a Kodak printer, good sized cartridges lasted a along time and excellent photo prints, but when it came to replacing the cartridge, it was actually cheaper to buy a new one, so that's what I did.
