Bluetooth radio transmitter $49 My mp3s are on my phone in my pocket. I get in my car and push play on the bluetooth transmitter, and the mp3s play from my phone to my car radio, all wireless.

For $199 you can get a mini cnc lathe

And everyone's favorite: 55 gallon barrel of sex lube

Nevermind y'all. This one's got the best reviews and it has bluetooth so all good to go! http://www.amazon.com/gp/product/B003PPGOC0/ref=cm_cr_asin_lnk

I've been rocking this one for several years now and it's going strong.
