Since a few of us at the office here dabble in guitar-slingin’ (some more than others; some just “Blackbird” and a few old Blink 182 songs), we thought it might be interesting to compare the eBay sales of a few top brands. We did this with the top-five-selling acoustic and electric guitars, and the result was Terapeak’s brand new guitar index.

As you can see (and might well expect), Martin and Gibson lead the pack in terms of acoustic sales, while Fender and Gibson manufacture the top-selling electrics. Of course, that’s combining total items sold with total sales — both of which you can view independently, along with average price. In reality, Fender electrics sell at a rate far higher than any other, but the higher average price of Gibson balances the two in terms of total sales.

Per usual, the index comes with a companion widget (shown above), which you can easily embed into any blog or webpage, as well as the ability to conduct your own Terapeak search; that means you can scour closed eBay listings for any other guitar brand you might prefer (or anything else on eBay for that matter).

You can view the full index here, and the companion widget where it says “Share” next to the two guitars. Enjoy!

Nah, relax, it’s nothing violent – Lion and Tiger still get along fine – we’re talking about Terapeak’s new Webkinz index, which compares the sales of critters across the eBay ‘kinzdom, from Cow to Gecko to Koala. The free-for-all consists of three separate events, with fun ways to sort and access info about all your favorite contestants. And, like our past indexes, it comes with an embeddable widget that fits easily into any blog.

CNN’s first July poll shows Obama up by six percent, but Terapeak’s new McCain-Obama index tells a whole other story. Not only does the index track and compare candidate-related sales and trends, its embeddable widget companion can be easily added to anyone’s blog to share near-real-time data instantly. And, it’s so interactive (and fun and colorful), even John King would be proud!

As the candidates scavenge America for votes this summer, each creates a new market for button-makers and book dealers — but that doesn’t mean the profits are balanced, or even close at all. At the time of writing, McCain-related items had sold 513 times in the last 30 days, for an average price of $8.66; Obama-related sells totaled 10,808, at an average of $19.69 apiece. So who’s controlling the market? Well, for one, the folks making those “Change” tee-shirts.

Put that one up on your big board, Johnny!
