Sony Cassette Adapter - works better in my car's tape deck than the Belkin, which had very narrow strips that only played on the right side.
Dynex 3' 1/8th to 1/8th cable - for the rental car's stereo, so I could play my MP3 player on the drive down to visit Tycho.
LaCrosse BC-900 Battery Recharger - very nice setup, I like the info for each cell site, the ability to charge at different speeds, and the free AA and AAA batteries.
Samsung WEP410 bluetooth headset - mine broke in my pocket, likely from being dropped the day before, so I got a replacement.
Automatic Transmission for '93 Mazda MX-6 - my car's transmission is totally dying fast due to the filter not getting replaced in 20k miles and choking off. This one is coming from New Jersey, and with shipping and install is still cheaper than a rebuild.
