You would be better off leaving the G3 versions alone and stick with a G4 machine if you do not feel that you can afford a new machine.
Whatever machine you finally purchase, please make sure that the CAPS LOCK button works. Posting in capital letters is considered to be SHOUTING, and we like it quiet around here.
Now, I gather you are looking for a laptop. Aim for the G4 iBook. You could take a look at the Apple store and see what they have available in their Refurbished line. There are some good deals there. Alternatively, you could look on-line at eBay for a G4 iBook. This will give you some idea of the price that these machines are fetching.
When it comes to upgrading, there is not too much you can do to a laptop, any laptop, other than add RAM and possibly a larger HD.
All G4 iBooks will do what you say you want to do.
