Many (most?) modern engines have knock detectors in them. If they are expecting higher octane fuel and you use something lower than specified, they retard the timing significantly to try to prevent pre-ignition. This results in a significant drop in power as well as mileage. The end result is that you'll pay more for the regular in loss of efficiency than you will save in cash. On my 1996 328i, the drop was ~20% in mileage (had a two week fuel shortage and couldn't get premium and I was pretty anal about tracking my mileage at that time). Premium isn't 20% more in cost (at least where I live it isn't). Add in the time spent making more frequent fuel stops and the potential for engine damage, and it's a money loser. Basically, follow the manufacturer's recommendations.

It's nearly pointless trying to explain something to a non-engineer when it comes to these things. The fact that they brandished a safety rating without understanding that it has nothing to do with QA makes it unlikely that they have the background necessary to understand your point. Never mind that my remark was primarily tongue-in-cheek.

I second TonerRefillKits. A very complete kit. The first refill takes a bit longer than others because the replacement toner is incompatible with the Brother toner so you have to spend some time making sure you empty out the remains of the original. After that, refills are quick. The Brothers are designed for easy refill (unlike the Samsung color cartridges which were both painful and prone to leaking toner). You should be able to get 3 refills out of a cartridge before the roller starts smearing. Then take them to OfficeMax or whatever. I've refilled perhaps 50 of them and it was a smooth experience. The only trouble I've had with the Brothers is that the toner level optical sensor can go bad giving you false refill indications. Covering the hole in the toner carrier with a piece of black tape can help work around that, but it doesn't solve your problem. Also, put the date of each refill on one of the provided stickers so you can keep track of how much life your cartridge has.
