I got one at Wal-Mart. It was the smallest one they had, and luckily it fit. It's one of those plastic ones that you attach a standard ratchet too. I wouldn't advise the screwdriver through the oil filter bit. I had a neighbor that did this, and all he accomplished was ripping the filter apart. In the end, he still couldn't get it loose. He finally had to call a wrecker service to get towed to the dealership. Hope this helps!
