If you have a straight shot into the basement you should be all right.
I bought a DJ-20, brought it home and then determined there was never going to be a way to get it into my basement. Brought it back and exchanged for a PM54A.
My basement stairs is U shaped with a landing half way down. No way to carry an 8' long crate down the stairs. It was just too darn heavy to get through the window. I didn't want to uncrate it as then there would be temptation to carry it by the table ends. It probably would not fit down the stairs even uncrated.
