How's it going?

Hi, I was a little busy. A little lol.
Well, I want to build my first DIY cheap laser.
I am mostly looking at dx.com because it's cheap and it's free shipping, something you don't get here in Croatia.
First off, is dx.com an ok source to buy from? If it gets next month who cares, it was free shipping. I just want to know if it comes at all and it isn't damaged that's all.
And another question, how do I know if this diode module will be ok for this driver?
Here's what I've decided to buy. Just a driver to choose now. I've yet to find it on dx.com though.

Ultrafire WF-502B host

650nm 9mm module

I've yet to buy anything online.

And of course, I forgot to check the batteries out.
I don't know which ones to choose, I'm looking on ebay for the driver.
I don't know where to start from...

That is a complete module, no driver required, just 3V such as 2 AAA batteries, it is also not the standard size 12mm modules we usually use.
