Where do you buy components?

There are some very nice electronics supply houses. Digi-key has an impressive catalog. But it isn't too good for obsolete parts, and the prices seem high. Jameco has a nice catalog, if they have what you want. I just bought all the chips (and some other components) to populate an Exidy Sorcerer motherboard from Unicorn Electronics (www.unicornelectronics.com). They had every single component I ordered, including some chips long out of production. Prices seemed good to me. And delivery was free and arrival was the same week. And the packing was all very neat in chip tubes. I just wanted to mention this good experience, since I think it is important to support businesses that support our hobby. What other sources are there that you all recommend, or disparage? Louis
