Continuues Printing Hack... IS IT POSSIBLE? Can someone rebuild my printer with a Continuus-Printing-System (so that it practically has an "Eco-Tank") for 222? ??? (see conversion instructions for similar HP printers: http://www.refillhouse.com/index.php?route=product/product&path=51_56&product_id=178) ((ps: I myself print with an Epson EcoTank at work, but: slow, mediocre print quality, feels like an 80.- model, but costs almost 300. Malicious tongues claim that the *fixed Eco-Tank print head* never reaches the 5 refill, which is enough for about 10'000 pages each. )) -> I'd rather buy a 250.- HP 8730 + 200.- for the conversion! Dear community, HAVE YOU NOTICED THE MARKET GAPS??? REBUILD GOOD PRINTERS, THEN SELL THEM, WHY NOT HERE, UNDER "SECOND HAND" ?
