Looking for good budget travel books on Ireland?

I'm going to be visiting ireland and getting around on trains and buses and staying in youth hostels. All the travel books cater to upscale traveling. Are there any good budget books on Ireland out there?

Borders Books has all that.

A really great book is "Go Ireland: On a Budget!" I really like the "Go" series and if you get the "on the budget" version it will have exactly what you're looking for. I've both Go Ireland and Go Italy and loved them both. They will give you the best places to eat for your Euro and great places to stay at a reasonable price. It also has lots of information on the sites and such that you'll want to see while there including landmarks, festivals, etc. The book is definitely worth purchasing! Have fun!
