Which module for shipping

Do somebody know which is good module for shipping I need to have this
I will have 3 geo zones and in each 3 types of postage!

How are you planning on shipping? by weight, flat rate, per item???

Yes, i was forgot to write that!

By weight!

You can use the built-in Weight Based Shipping for this. Just create three copies of your geo zones in System > Localisation > Geo Zones like this:

Zone 1 - Standard
Zone 1 - Express
Zone 1 - Overnight
Zone 2 - Standard
Zone 2 - Express
Zone 2 - Overnight
Zone 3 - Standard
Zone 3 - Express
Zone 3 - Overnight

Then enter the rates for each in Extensions > Shipping > Weight Based Shipping. For example, if you wanted to charge 1.00 for the first kg, 3.00 for 1-2 kg, 5.00 for 2-3 kg, etc. you would enter:

1:3.00, 2:3.00, 3:5.00, etc.

I see couple Extensions, can you suggest me best of them? I first time used OpenCart. I guess that I need to bought this, is it correct?

Or you maybe know some module that have and by weight, and flat, and per item, and cost something like just by weight?

If you know can you post one link just by weight, and one which have everything?
Thanks.

You can use the built-in Weight Based Shipping to do what I describe, so you don't need to purchase a commercial extension.
