Getting a mill with my tax return this year - looking to go a small step or two above the mini mills, of the two brands above, what are the pros / cons and recommendations by those who use them? Thanks!

I went out and purchased the Grizzly G0704. It is a very nice small mill. I was about to purchase the Little Machine Shop 3960 Hi-Torque mini mill. When I started pricing out the stuff I needed to just get the 3960 to work, I was already up to $930. Basically, the 3960 needs the airspring kit in order for it to have any reasonable chance at stability.

So ... I went and purchased the Grizzly G0704. It is bigger, sturdier and also comes with a very nice base. The G0704 is not as decent as a Bridgeport, but it does fairly well, if you are very careful with your setups and knowing when to lock everything down.

I had the G0704 and sold it and bought a Bridgeport FOR LESS MONEY. The 0704 is a toy, the 'port is a machine. Just wait for the first time you kill a set of those PLASTIC gears.

just got the LMS, has a few better features than the grizzly. i also got the tooling package. i may upgrade to a larger machine down the road but this will work for now. dont forget to get a dial indicator to tram the machine before use.

I'm still chugging away on my HF mini. Slow but gets it done.
I have a stationary belt sander from Grizzly that had an issue. They were awesome for customer service.

Any chance you could share where you sourced your Bridgeport?
(PM is fine ;) )

Craigslist or Ebay, some of the machinery forums will have for sale items. If you look for a month, some real nice stuff will appear. If you want instant gratification, probably not the place. Newspaper ads were the only source when I bought my B-port. Only looked for 5 years until I found it.

The high torque solid column (non tilting) LMS mill is the best of the small mills you can buy. I have an X3 from HF and it's fine but if I had to do it again I'd get the LMS mill. Torque is king.

Rigidity is king.
Torque won't matter when the machine has deflection while cutting...

the LMS hi torque mill is just a beefed up X2. The X3 is a superior machine.

I bought a Grizzly G0463 (Sieg X3) and converted it to CNC. Im using ballscrews from cncfusion, 23lbin servo motors, Gecko G320x drivers and controlling it with LinuxCNC. I love that thing. Ive completed a few 0% lowers with it.

Im clearing out a magwell and FCG tonight. Maybe I'll get some pics. Heres some quick links for the first run, and some AR lower work. The servos were not tuned, so they were kind of jumpy. You will hear them jog the C clamps around on the second and third vid. The three axes all use the same type of servo (23lbin MCG servo w/Renco 5000count encoder). I plucked those new from ebay at $59 each with encoders.

First run. First time all 3 axes were connected.

Its a mess at the moment. The control box with the servo drivers is at the bottom (Coolermaster PC case with 4 power supplies, parallel port optoisolator and 3 Gecko G320X drivers). The PC on the right is running LinuxCNC. I either control the mill with the keyboard or run GCode. I can also just type in the coordinates and move it into position. The column and two exposed servos are covered with EPDM rubber sheets (Had chips blow out an encoder once). Theres also a Kool Mist coolant system on it. Im just getting it ready to clear out a magwell and FCG in this picture. There's a completed lower to the right of it.
