Unless you're really picky, sloppy about equipment maintainence, abusive on equipment, or don't follow the directions at any point, I'd recommend Lee.
Not that the others are inferior, it's just that Lee has been serving me well for years. Sure I've run into problems, and occasional defective parts. But Lee backs thing up. Their products work. And by the time they wear out they've long since paid for themselves many times over. Plus Lee will recondition any of their products for 1/2 the manuf. sugg. retail price - which is something like 2/3 or 3/4 the cost of new.
If you get a Lee mold, I'd recommend getting two. Even if they're the exact same caliber/bullet shape. With two molds going you can set up a pace to really crank out a lot of bullets. Fill a mold, set it down, fill the next mold, set it down. Pick up the 1st mold, cut sprue, drop bullets, refill, set down. Pick up the 2nd mold, cut sprue, drop bullets, refill, set down. Back to the 1st mold, then the 2nd, then the 1st, and so on.
With only one mold, I found what slows me down is waiting for the lead to freeze. By operating two molds at once, you aren't standing idle. The price of Lee molds also allows you to buy two.
For a lead pot I use a Goodwill stainless steel saucepan, placed over a $13 propane campstove. The stove is hooked up to a 20# tank so the propane is cheap. The big pot is nice for catching drips of lead and cut sprues.
