The fact is I do listen. Since you said 32mm was too big I've spent a week investigating and learning about machine design. It turns out that 32mm is probably fine, but I will most likely go for the slower speed, higher acceleration 25mm option.

If you tried reading a post now and then instead of flying off on a rant, you would know it's not a 3500rpm machine with 32mm ballscrew.

And once again you throw up barriers that don't exist. I'm not asking for a $4000 machine. I'm looking for best overall value that meets my needs. And that's lifecycle costing, so it includes resale value.

When I add taxes and shipping the machine I'm looking at is about $6000. On paper it meets my needs. So if there was a machine going for $8000 that I thought was a bit betterr, or that I could get sooner, I'd snap it up. A $10k machine would have to be considerably better. As it is I'm happy to go with the best option I've found so far and take the risk that eg the electronics might need upgrading if your predictions come true.

I appreciate you are trying to be helpful, but once you've given out some advice you have to let it go, you can't dictate what I do with that advice.
