Without thinking of airplane tickets, I want to spend the least fee I can afford to travel to Europe.

Does anyone have experiences about this?

I usually travel one country about one to two weeks and if I get there, I only pay for the cheapest food and accommodations.

Please advice me for this.

Thanks.

Hi
The worst and possibly more expensive part of a journey is getting out of the UK. LOL
the best website I have ever found for trains (mainly) is www.seat61.com.
It talks about train timetables, destinations etc for nearly every country in the world. For example I used it when I went back packing around SE Asia a few years back.

Custom tour sites I find more pricey, for instance by train from Bournemouth area to Rome would be about £650 return by train.
There are coaches but at present I cannot find a "period" travel ticket that allows you to hop on / off.

Only a little help but hope it does anyway.

Learn from yesterday, live for today, hope is for tomorrow else what is left if you remove a mans hope.

Any eastern Europe country is fine. Or Portugal. 
Train ticket you can use Interrail.

Enjoy
