I have personally always liked using WinPack. You can download it here:
http://www.peaksys.co.uk/It is shareware so it will put up a nag screen now and then until you decide to purchase it, but the software is fully functional to check it out and decide if its right for you. Its a nice and easy user interface that is simple to use.
And after all, that's what you want when your first learning isn't it? Have Fun...
