Good and Bad websites

I've been set the task to find 3 good websites and 3 not so good websites to do with my chosen topic and explain why i have this opinion of them.
Good

• http://www.bluebanana.com/
• http://www.grindstore.com/bands.html
• http://www.thisispulp.co.uk/browse/mens-bandmerch_12_0_0_na_1.html

These websites are all really easy to navigate around, you can search for things and the links work. All words are clear, they also all have tabs that make finding things a lot quicker.
