Well what I'm looking for is something like Editplus but a bit more rubust.

See, Editplus does a nice job of colour syntaxing my code, even to colouring the variables not just the keywords.

Its certainly not a CPU hog that I've noticed and if anything it makes it easier to debug because it makes it easier to spot syntax errors - it doesnt try to correct them.

There a few autocompletes, mainly for if, while and fore statements which are generally O.K.

But, I think a good IDE makes you more productive. In some languages there are a lot of keywords and so on to learn and having a friendly reminder save having to hunt through a manual or book. Especially if like me you can work for 3 months on one language and then have to swap to another afterwards.
