I bought a big worktable (3.5 m long) mounted on wheels with the possibility to extend section to have additional surface. very heavy object, but very sturdy and with a little modification i added some storage area underneath the table.
Very happy with the investment.
Acquired a pretty expensive Drilling/Milling machinel (OptimumMaschinen), but again very happy with the tool.
I also bought a bench grinder (Makita), a band saw and a belt sander (again from Makita). The band saw is actually and overkill and i will look for a smaller model with the vertical band saw.
Very happy with the vertical tank compressor too.
