I use that machine a lot, its mostly a time issue for me. I can get home at 6pm and my kids can be eating pizza before 7... With a rolling pin the dough moves around and rips if you rush it, plus its a lot of work, I just pop the dough ball through a couple times and you can make it what ever size you want in less than a minute...
PLUS it expands what you can do, like by hand I dont know anyone who can get uniform flat breads like that machine can make, they cook so evenly, I put the oven around 400 and cook them on the rack just flip them over after 45 seconds and within 2 minutes they are done, bag them up and have sandwich wraps all week... You can get a 12" RD hand roller for around $500 on ebay.
That was one of the first commercial kitchen machines I ever bought, I have sworn off of home equipment, if I buy something for the kitchen I make sure its commercial, I burnt out a bunch of food processors and mixers in the past years, now with the commercial stuff its seems to last forever and do a better job...
For instance my robot coupe r2n dice, it was $1500, BUT I will never have to buy another one, and it works like no other I have ever used, plus its so quiet and strong... 10 qt. planetary mixer, I burnt out a couple kitchen aids that were $500 each, so I went to the planetary mixer and its mixes anything I throw at it...
I do cook a lot, I haven't bought store bought pizza, bread, wraps, cakes, ice creams, pasta, ect in years... I even make my own ravioli 25 lbs at a time...
