The pen tool can seem intimidating, as it works quite different that what you are used to. Once you understand the concept though, it is actually the easiest and quickest way to make most complex selections. I only use the lasso tool for rough quick selections, where I don't need a very accurate selection. I find it too tedious to use for precise selections. The selection mask can be easy to use, but it also can be very involved, and requires a bit of practice and intuition to master. I really recommend that you learn all of the various selection methods, as the different methods are useful in different situations.
There are many tutorials for the pen tool in books, and on the web. I think that there are even some here. Here is one that you might find useful
