I can't say I've ever used Advanced, but I've had good luck with O'Reilly's. They've even found cross-referenced parts for vehicles that aren't in their inventory system--f'rinstance, a few months ago I needed an oil filter for my 8N, but O'Reilly's doesn't stock tractor parts, so their inventory system doesn't list them. The guy at the counter went to the Wix Web site and looked up the part number, then found the filter in stock (for another vehicle).
