18x8 & 10x8 insulated raised panel steel doors will be easy to lift manually. That is what the springs are for...counterbalance. Since you are going to put these in your man-cave, I would suggest going with torsion springs as opposed to extension springs (safety). There are not as many garage door manufacturers anymore, and most of the products are identical. I have been installing General Doors & Richard-Wilcox Doors almost exclusively. Make sure you have a minimum of 12" above the door opening for the cross-header hardware (springs, tube, cable drums). and wait until after the doors are installed to finish your ceiling.

Since I retired I have gotten back into the garage door business.
