1st Build, Second machine

[Jonathan]

Thanks for mentioning Collet size Jonathan as that is probably the best reason to move up from the 1.5Kw unit even though I really don't need that much more power. Seven millimeters is just not big enough by one millimeter to do the range of tools that I have reason to use.

Not that I want to change your decision, but the collets on the 1.5kW are ER16 which goes up to 10mm:

(I think you were looking at ER11 which is up to 7mm)
For most people over 10mm is critical as it means you can use 1/2" router cutters.

Remember that the available power output from the spindle is roughly proportional to the spindle speed, so if you're starting with 2.2kW instead of 1.5kW you have more power at lower speeds. So saying 1.5kW is more than you'll ever need I think is not quite true as it doesn't take into account this power reduction.
