Source for components on Internet?

I've had bad luck with mouser... I called and ordered a DC-DC converter in an 8 pin DIP, next day delivery, and received 7805's instead (plus the rest of my order). I called and was told the replacements would "be shipped out today". I called the two days later and was told the same thing, the third time I called I was told they had already shipped out. They arrived, UPS ground, free of charge, but they were STILL 7805's.... I called and bitched again until I got someone who understood the difference between a 3 pin TO3 and an 8 pin DIP, (are you SURE it isn't a compatible part?), got her to right down an alternate part number (the 'A' version versus the 'B' version, tighter specs), and what was NOT an acceptable alternative... The 'A' version arrived about a week later, again shipped UPS ground, no refund on the next day shipping. YMMV, Clint On Mon, 17 Jun 2002, Gary Hildebrand wrote:
