Keep a spare then? Unless the proper ones are less than twice as much as the cheap ones and don't charge for repair you're still winning. I bought my second one and it arrived in about 4 days, not bad I thought.

If you really need lots of torque at low rpm then having the vector drive helps, so that's one reason to get one. Still if you want to do that get the 2.kW spindle so you've got more power at low rpm to start with (and the bigger collet of course). They come up cheap on eBay occasionally.
