The easiest in my opinion is myetherwallet and I highly recommend it for participating in ICO's. However, every other ERC20 compatible wallet will work also.
Thankyou for the replies, I have used that site before. I thought I might forget a bit too easily the procedure to use that site so found a list of suitable token ETH wallets and imToken wallet on Android looked good and of course I backed up the mnemonic phrase which I think is enough to be safe.
Hopefully I'll get a bit familiar and confident with the systems later
