NAS - recommendations please

[Sebastian]

Hi all,

for a while now I've been looking into buying a NAS for the growing
amount of data.

I was thinking of something like QNAP TS-209 Pro
[http://www.smallnetbuilder.com/content/view/30181/75/]
but as funds are short and the need for storage is pressing I was
thinking that there should be a less expensive solution out there
which still does the job sufficiently.

When I look as e.g. Officeworks I can get a external 3,5'' drive with
500GB for less than 150$

So is there a decent NAS out there which brings ~500GB and is still  ~200$ ??

Cheers,

Sebastian
