I keep an old thinkpad laying around offline and do the following Create unsigned transaction(online). Sign it (offline). Broadcast it (online). There will be instructions for any wallet software how to do this on bitcointalk or their own documentation. After each txn backup the wallets to some other offline/cold storage in case the thinkpad dies. If you had millions of coins you wouldn't want to do this obviously due to usb attacks but for my <$1k wallet good enough. There's also QubesOS, can keep wallets running in different VMs
