Lowe's sells a portable unit that seems to be a good one. It is made by Danby. it is rated at 12000 BTUs and also works as a dehumidifier, fan and space heater. My brother has one for his home office and is very satisfied with it. he bought it on sale earlier this year for around $500.00. That's more than for a comparable window or wall unit, but not too out of line for portable units. They tend to be expensive no matter whom the manufacturer is. As to cooling to the low 60's or lower, I don't think that a portable unit will do that. Brother's unit hangs around 70 max on a hot day though he keeps it set around 75 most of the time. I have a 15000 BTU wall unit cooling a space that is 19' x 9' and at max cooling the lowest the temp gets is about 65. at that setting it runs pretty much all the time and the power usage is enormous even though it is energy-star certified. I keep it set on about 76 when I am home and turn it off when I'm not there.
