WordPress plugin for easy Magento database connection

Here are a few options to try if you are looking to Integrate Magento and WordPress together:

• MageEnabler is a WordPress plugin that makes it easy to init(); Magento.
• Inchoo’s integration connect2MAGE.
• LazyMonk integration via Magento Connect module for WordPress to Magento.

Personally I’ve had the best results with MageEnabler and LazyMonk’s integration, as both won’t cover everything you may encounter and want to work more closely together.
