Ok...I have wanted to buy a laser printer for a long time but I've been reluctant becuase they are obviously pricey. But I now have the option to buy a gently used Lexmark laser printer from work. So how do they compare to the rest on the market? I'm not sure of the model number, but I know that it's around 1 year old. It prints about 5000 pages per toner cartridge, which I'm told is pretty good. Is this a completely dumb purchase...should I just stick to bubble jet printers?
