The right tools for the job

A slight off topic question but I've just invested in the repair kit for several items after abusing my better halves tools from his RC cars.

I've got a UV heat lamp and roller for those loca repairs, heat gun but now need to think about the next piece for my collection.

I need to look at reflows, autoclaveable and ultrasonic are there any other pieces of equipment I should look at to help make repairs a lot easier.
