However, shortly after finding out that a couple of new sources for <a href=\"http:\/\/www.ladyada.net\/make\/x0xb0x\/index.html\">x0xb0x<\/a> kits I happened to listen to a few 303-heavy tracks by The Crystal Method and decided that I might as well grab a kit while they&#8217;re available. I mean, eventually the world is going to run out of those discontinued transistors, right? It seemed like a reasonable rationalization anyway.<\/p>\n<p>So I ordered a kit from <a href=\"http:\/\/x0xsh0p.de\/\">x0xSh0p.de<\/a>. I corresponded with a fellow named Christian who was very polite and answered my queries promptly. It took it a couple of weeks to make its way across the Pacific, as expected, but it arrived in fine shape thanks to its good packaging. It&#8217;s a well-done kit; the parts are organized in many small, neatly labeled bags and there&#8217;s a hand-checked and signed BOM verifying that everything is present.
