Open Source e-commerce system: Magento

I mainly prefer MS .NET development, but i have to agree that Magento is a great open source e-commerce system built using PHP. I have noticed an increase of performance using Apache and PHP for e-commerce websites. Sure PHP is still spaghetti code, but magento was able to design the architecture quite well. Plus there’s a vast community for add-ons and support. Another perk is that its easy to find PHP developers, and at a much lower cost compared to .NET developers.
