Seeking suggestion for headset and bottom bracket press I'm looking for a suggestion on a single press tool, good quality, that will allow me to press fit a Praxis PF30/BB30 conversion BB and also a headset on a nice titanium frame. A single tool would be much easier on the budget.
I've used the Park Tools BB30 tool thing and a bar clamp (eg this) to squeeze pressfit bbs in. I can't speak for headsets though. 

I've found that local bike clubs are a good way of gaining access to specific tools like this. Especially as they can be expensive considering how many times you might need to use them. And you get the bonus of someone who's experienced fitting things like headsets before. People are usually keen to help a fellow cyclist out.
