Northern Tool offers the Kindling Cracker King XL Firewood Kindling Splitter for $119.99 with free shipping. (Kotula's offers it for the same price with free shipping). That's the lowest price we could find by $26, although we saw it at this price in February bundled with a $10 Northern Tool gift card. It features a 9" inside diameter.

Note: Need a smaller cracker? Northern Tool also offers the base model version for $79.99 with free shipping.
