SHARP UX-B20 RIP OFF

On April 28, 2005 I purchased a Sharp UX-B20 Plain paper inkjet fax from Staples for $79.00. It had a $50 rebate so I thought it was a bargain at net cost of $29.00. The low ink light started to flash after about 10 pages so I went back to Staples and was told the factory cartridge holds very little ink. I purchased a new cartridge for $33.00. Now, 20 pages later the "ink near empty" message flashes. Calling Sharp Service Center was a waste of time! Buyer beware, this fax is no bargain. 30 pages = $62
