OpenSearch Plugin for Amazon Instrument Search
We've created a search plugin for Mozilla Firefox and IE7 that lets you search the musical instruments section of Amazon by default. This might save a few seconds for those of you who are specifically looking for instruments and don't want all of those extraneous categories to show up.
One thing you may not be aware of is that just like 'used and new' books, used instruments can also be found on Amazon.com. The selection isn't as extensive as eBay, but you might find a hidden deal.
