Yet another question about what spindle/VFD to buy... is there a sticky thread on suggestions made by the forum users and their experiences, maybe there should be one if not?

I'm in the market for a spindle and VFD and have looked at the cheap Chinese models and wondered what the next step up was and who the players are in the market.

Are there decent models available for $500 - $1K, spindle and VFD or is that pipe dream? Does it make sense to go with a Chinese spindle and quality VFD?

My main materials are wood and aluminum but I would also like to drill and possibly cut some steel so I think I need a low RPM range for sure, this is a hobby so no business purpose here.

I've read discussions about the number of poles in the spindle and it seems that the 6 pole units somewhat would fit my purpose but I think I'm giving up a bit in the top end RPM. Maybe the 4 pole is a better option?? I'd like to understand the differences to be able to make a better purchase for overall usage.

So I'm thinking the following criteria...

Air cooled with Electric fan
3kw = 4hp
2.2kw = 3hp

4 pole (8k-12k rpm) 15K RPM MAX
6 pole ( < 8k rpm??)

- Reasonably priced for the hobbyist
- Quality electronics

Thanks for any input and suggestion.
