I have to agree with Bankole here. Spending money collecting a lot of sub-par & out of date tools may not be your best investment. If you really can't afford to buy a legitimate PC-3000 which will have the potential for getting updates, perhaps you might consider MRT tools. Certainly isn't as good as PC-3000, but can still handle a lot of basic things and you can learn along the way. Plus, since they've effectively copied the PC-3000 look and layout, you'll become familiar with the gist of things.
