thanks for the advice everyone, I ended up getting Genki, and quite pleased with it. It seems to cover all the bases to a reasonable depth for me, and its pretty cool getting a lot in one big book.
I would really recommend trying classes, but you might find it depends a lot on the atmosphere of the class. It can be really fun, but you might need to try different classes before you find one you like.
Sorry if it's been asked already but I'm going to start learning Japanese seriously and was looking at taking a course this year. Before I pull the trigger on it, is taking a course a good idea or is it better to self teach myself and then take the test for the qualification?
