Willing to try some DIY?
Check out the CMOY pages. Most of what you'll need is at the RadioShack. The rest? A single order to any one of the electronic vendors. Than you can get into 'opamp rolling'. Buying the tools, for those without tools may be expensive, but you'll never have to buy 'em again.
You can build one for 30$ or 40$. It should drive the Grado phones just fine.
