Which wordpress plugin should i use to get RSS subscribers?

I want email subscription plugin for wordpress that can put "Enter Your Email Field" or a big RSS button on sidebar, simply to encourage users to Subscribe. If any other method, please let me know.

Something like on Top Right side on these websites

Having a big RSS icon on your blog helps!

 

Good Idea!

 

You ca also try feedburner for subscription

 

i think use some script for rss.

 

Agree.. I used it in my blog..
