hey cuz, Haven't you replaced your incandescent scew in bulbs with the curly fluorescent replacements? A lot less susceptible to sparking if you break one.
At the stage of completion that you have Amos, I wouldn't invest in a lot of tools that you may never need again. So, unless you're buying another LBC, or going to go into the TR repair business(and believe me the quality of your work is better than a lot of shops I deal with regularly) I see no need to invest in a lot of tools that are going to just be sitting.
