I posted a while ago about buying a scan tool...did some research and I think I found a
good one.....(going to buy it, haven't yet)

Its the Equus 3145.

It reads the EEC-IV codes and displays them on a digital screen.
Its 33 bucks from http://www.midwayautosupply.com

You can read more about it at: http://www.iequus.com/item.asp?cid=10&pid=3145
or go to www.iequus.com and put "3145" in the search box

This thing seems much better than that POS actron thing that beeps at you. [:'(]
what a waste of money, you can do that with a volt meter
....
anyway, I'm not good at the voltmeter thing, so I'm trying this...
