gotta love Harbor Freight, especially for those tools that you might only use once for a project. I also agree with you on the heat shrink, its decent quality and at a good price. I prefer the 'marine grade' with the adhesive/waterproofing.
One thing I would add to the no-go list is drill bits if you intend on using them on metal. they just don't hold an edge... (they work fine if you are drilling wood, or maybe even aluminum).
