I wasn't too comfortable with the hardware being "out of my control" during shipping etc., so I used other hardware wallet solution - simple, cheap/free and extremely safe:

Everyone has old unused laptops laying around. I took two laptops. On both I formatted hard drives and did clean reinstall of the system. 1 of these laptops will never be connected online, network adapters are disabled. On the other laptop, go straight to download section of electrum wallet. Download wallet and verify the authenticity. Take clean USB stick, format it and put downloaded electrum wallet there. Take the usb stick and insert it into the first laptop (the one without internet connection). Create wallet. This laptop will NEVER go online. If you are totally paranoid you can destroy the USB stick

The laptop with the internet active is used for Electrum - watch only wallet. This type of wallet has no access to your private keys, yet you can see your balances and iniciate transactions (these have to be confirmed via confirm file, created on the laptop with the original wallet).

This process should be reasonably safe.
