<div> <font face="Arial, Helvetica, sans-serif">Hi Thanks for the reply,<br>
These are the two I am considering. I ACTUALLY wanted a CNC but as was mentioned, the additional tools needed, (dividing head and such..) will add substantially to the final price of having an actual useful tool. So CNC will be a pipe dream until I can work through adding the stepper motors and electronics. <br>

Weight wise, 105 vs 150 lbs could be a challenge but I intend to take the head off whenever I move it and that should be a rare occurrence once I get it set up. Your comments about your grizzly are very useful. I'm leaning to the bigger model now, which, as it happens, is very similar to grizzly.<br>

How much do you want to spend? How heavy a machine are you willing to deal with <br>
(i.e.,<br>
50lbs, 100lbs, 500lbs, 1500lbs ? )<br>
<br>
I have a Grizzly G8689 <<a href="http://www.grizzly.com/products/item.cfm?itemnumber=G8689&site=grizzly" target="_blank">http://www.grizzly.com/products/item.cfm?itemnumber=G8689&site=grizzly</a>><br>
that I'm pretty happy with but I had to do a number of mods. Also for building <br>
the jBot<br>
robot it was not quite big enough to mill the 5x20 inch chassis plates and we <br>
had to use a<br>
big Bridgeport. But for all the small parts it was fine. Dandy, infact. <br>
Mostly aluminum<br>

fiddley bits.<br>
<br>
Generally bigger is better if you have the $$ and the space and can handle the <br>
weight.<br>
<br>
Do you have any particular machines in mind?<br>
