Personally I think everything that john Walkenbach writes is very easy to get on with, and caters for newbies through to advanced.
He has two books currently that I would happily recommend:-
The first being Excel Bible 2000 Gold Edition (I can only find it on Amazon in the UK, not the US though), which will cover pretty much everything you could ever want to know about Excel. It also comes with a CD with truckloads of examples. Don't confuse with the Non Gold Edition which is not so heavy on VBA. Also don't confuse with the Excel Bible 2002 edition that John didn't update, and as a result doesn't have the examples CD (Also this book as well is not too heavy on VBA)
The second being his 'Excel 2002 Power Programming with VBA', which despite the title does in fact cater for beginners through to Advanced. I think this one is great.
I find his style of writing very easy to get on with, and whilst we are all different, this just works for me.
