Info on Chinese suppliers, their reliability and reputation

[Jonathan]

Any recommendations on where to buy a spindle ?

Yes.

What power should I consider for cutting MDF ? (and as with most people , there is that desire to cut ally ! lol )

Depends how fast you want to cut it, but generally people get the 2.2kW spindle simply because it has the larger collet size.

should I get the VFD with the spindle ?

Yes. I don't know anyone whose broken one in normal use.
