I've tried to stay out of this and let the chips fall where they may BUT,
The next (as well as all the rest of them) buildoff saw needs to be something readily available and inexpensive enough for the average Joe to get hold of!
If you want to exclude about half of the folks that would like to come out and play, make it something like the 084/088/3120 etc.
I couldn't even play when the stakes were as high as an 066/660.
I would suggest something like the OPEN PORT 6400/6401!!!!!
That is a saw that can be picked up for $150.00-$250.00 in good running condition and is readily available.
The 7900 is a great idea but even a decent used one is going to be around $400.00.
I am lucky enough to have a couple just waiting, but not everyone is.
Do what you want and I will be happy to watch but I think it would be better to let poor guys play too.
