External HDD case

Hi,
I want to buy an external hdd case, 3.5".

I basically just want to keep buying HDDs and using the case to transfer data.

I need a case that is sturdy and preferably with eSATA support.
Something like what seagate and all use for their 3.5" 1tb externals.

Budget is up to 3k for only the case. Give or take a few 100.

Any suggestions?

Thanks.
