Jason,
I would guesstimate about 330 squid but it could go a lot higher. The machining season is upon us and it just depends how many idiots are knocking about.
Would it be worth saving your pennies a little longer and go for the updated X3?
I haven't really looked at what the main differences are, but it might be worth checking out, just to see if it justifies the longer wait.
It is a real major purchase that will last you for many years, and if you decide you really wanted the later machine, you could be kicking yourself for a long time. I was going for the Chester 626, then a windfall came my way, and I got the 836. Looking at it now, if I had gone for the 626, I would now be regretting it, and saving up again to get the one I have ended up with.
If the extras don't justify the higher price, then you can still go back to your original choice.
