Depending on the thickness of your floorboards anything from a 38 to a 50 mm brad can be used.
GMC are ok for a one off job, but beware you may end up taking 3 back before you get a good one so make sure you purchase from somewhere which has a good returns policy, as with most tools you get what you pay for.
Another option to buying is to hire a tool depending on how long you think you will need to lay the floor.
