iPod What is the best iPod Universal Dock?

I'm an iMac owner and I'm looking to buy an iPod Nano (silver/black) for easy syncing with my music..

But after a small research i noticed that there is dozens of docks out there, some with speaker, some without..

I wanted some input on what would be an iPod dock that will match my imac without taking much space..

Even thou i don't need speaker, They might be useful at some point.. but like i said i want it just so I can sync it. But i don't want a big dock on my desk since i like the clear look..

Any recommendations.. is the apple OEM dock the best choice?

Thanks in advance.. recommendations with links would be great..
