MIT Flea Market or Swapfest.

MIT Flea Market or Swapfest.

Where can you get an amazing deal on a used PC or electronic doodads  on the third Sunday of the warmish months? At MIT’s legendary flea market or swapfest. At MITFlea.com, you can get the scoop on buying or selling electronics, amateur radio components, and computers a few years old with plenty of juice left for most users.

And deals are to be had. The Boston Globe reports August deals of a $250 Dell Latitude laptop with an Intel Pentium 4 chip, a gig of RAM, and a 40-gigabyte hard drive or, for $300, a Hewlett-Packard laptop with a 14-inch screen, an Intel dual-core Centrino processor, a gig of RAM, and an 80-gig hard drive.

Who sponsors this? The MIT Radio Society, in conjunction with the MIT UHF Repeater Association, the MIT Electronics Research Society, and the Harvard Wireless Club, hosts the swapfest on the third Sunday of each month, April through October, at the Albany Street garage on the corner of Albany and Portland streets. Next date: Sept. 20.
