owc data doubler alternatives?

A few month ago, I bought the 120 GB OCZ vertex 2 SSD. And replaced the 7200rpm 500 gb stock hard drive with it. I am really happy about the speed, but there is not enough free space available. So i looked up on the internet, and it turns out that I can replace the optical dvd drive with my 500gb internal hard drive by using a adaptor. One of the best is the OWC data doubler, but the think is, I live in Europe. This means that shipping from USA will cost 15 dollars, the country I live in will charge 25% VAT which is another 20 dollars, and on the top of that my country will charge about 35 dollars import fee!! and there is 5 dollar extra on the import fee as well.

So the 75 USD OWC data doubler will cost me 75+15+20+35+5= 150 USD!!! that is double the original price!

So I am wondering if there is any high quality alternative to the data doubler, which I can purchase in EUROPE? (If it is in Europe, my country will not charge the import fee so I don't have to pay the unreasonably high 40 dollars import fee)

I do not mind paying slightly high prices, but 2x the original is just ridiculous.

Thanks in advance
