It all depends on what you'll be doing with your mill, if you'll just be milling guards 95% of the time, and your budget is under $2K, I would recommend something like this:

(The Travers mill didn't mention what size T-Slots are on the table).
Other considerations:
Get the biggest / most practical mill you can afford for your purposes.
Bear in mind, if you may move, a big ol' heavy machine can cost up to $400+ to move
Smaller machines, especially those on stands (and can be separated) can be moved easily with a cherry picker and placed in the back of a pick up truck or minivan
Used a Sherline mini-mill for many years because I was making knives out of an apartment, but you can't mill stainless steel well with it -only brass and nickel silver.
Stepped up to a full size Jet clone of a Bridgeport, it's a good machine, but I kinda wished I went smaller. Moved a few times and had to hire a machinery mover with a gantry system to help. Cost $400-500 each time.
Another thing to consider, I really like my Kurt Vise, personally have a 6" -but wish I went smaller with a D40 4" vise instead.
My machine is large enough for making Integrals, and I made a few, but I really didn't need such a big machine as 98% of the work was for just fitting guards.
I think this would be a fine machine to start with, make a few knives, get better at it, then upgrade the machinery as funds permit. I really like the included DRO for the price, makes precision fitting of guards possible.
Bob Loveless had 3/4 sized machines, he really liked his Jet mill, which is still in use today, it's a 3 phase version of this:

I'd also recommend you save some funds for:
A D40 4" vise, t-slot nuts and studs for the vise, a 3/8" R8 collet, 1/8", 3/16" and 1/4" end mills
Have fun!
