Just get a dope old steel frame. Square taper bottom bracket for life. this would help for an external bb. But just go square taper. I had almost that same kit and have replaced most things over 8 years, but the ratchet bb toothed tool (in the top left corner of the second pic of your toolkit link) has lasted me this whole time (maybe like 50-60 bb swaps). Just go sealed square taper and make sure the cups aren't plastic... but if u r cray about the bike weight or whatever frame you have idk...
