Hello,
I'm still wondering between Arduino UNO R3 or some Arduino compatabile board...
Only two reasons.
One: Because it supports the project through which the board designs and software base have been developed.
Two: Because you get something of reasonably guaranteed quality.
And it pays towards this forum.
some "fake" boards behave just a little bit different which makes some bugs harder to tackle.
When I want a new car tv phone etc. I always buy them from the guy in the back alley.
Because if you need support you have hardware that is likely also used by the community; we then have a ready reference to assist. Clones & fakes make finding and fixing problems so much more difficult than it needs to be. Buy-in once to authenic, then use clones to your heart content... You'll be able to diagnose a hardware problem yourself!

I just thought I can make a breadboard wirh Atmega328 and FT232 
Sure you can, and it's a good project to do.
You will learn a lot of new and fun things.
Lots of help here if you run into problems.
However, if you want to buy a "new" UNO you are urged to support the original designers of the board.

You can.
And as it has been said, it is a great thing to do.
But it depends on your level of experience.
If you are new to electronics, IMHO you should buy an original Arduino Uno R3 for a start.
It will work!
That way, if something isn't working, it is not likely to be the hardware, and it will be much quicker to isolate the problem.
So far, I have:
2 original UNOs
2 UNO clones
1 Mega
5 Pro Minis
A bunch of ATtinies that has had Arduino code loaded on them.
...... and a handfull of Atmega chips, waiting to be turned into standalone Arduinoes.
But I haven't felt ready for it before now.

Missed out on the partridge in the pear tree. XD

You can, but the 328 better have a bootloader on it.
Otherwise you will need a ready-built Arduino (or an ISP) to put the bootloader on it.
so... which is the best HOW-TO to make Arduino on a breadboard? 
Nick's of course! 
there's an Arduino to program the chip but i see it's only to write the bootloader.
I can also write the bootloader via USBasp (which I have) and then use FT232
Am I right**?**

Aaaaargh!
Now I'll go around the rest of the day, subconsciously trying to fit the list to the tune!
and after having connection through the FT232, what board schould I choose in the Arduino IDE ??
After you bootload the chip, select Uno as the board type. I bootload all my '328P boards as Uno. Even re-bootloaded my Duemilanove's as Uno,
and UNO will work via FT232**?**
thanks 
Sure - that's what the Duemilanove is - a '328P with FT232 as USB/Serial interface, instead of '16U2 programmed as the USB/Serial interface. The Rx/Tx pins don't care what happens on the other end of the Rx/Tx lines.
I thought Arduino UNO but now you said Arduino Duemilanove
sorry, I'm lost again...
