I have not used Profoto since about 1989 and even then my experience was quite limited. But with that said, as with most tools the main advantage of buying "higher end" is in flexibility, the flexibility of being able to adapt to differing situations. Way back, my personal choice was Novatron. Unfortunately I am beginning to experience problems with them, after only a quarter century of heavy use. (Maybe I'll complain to Novatron about that!) They traveled with me and performed completely reliably while I did commercial work. They worked with no problems at all in lighting everything from small product to groups of 6 or 7 people. My Novatron powerpack had only two power settings, full and half strength, with two more on the heads. I found that to be more than adequate. They are not the brightest lights available, but easily allowed me to do anything I needed to do.
Yeah, the 100 watt modeling lights are sort of dim, but I keep ambiant light low while shooting and they work. I'm rarely surprised by sneaky shadows. They have allowd me to 'see' glare when shooting a lot of oil paintings and other artwork and so forth. Brighter would be better but again, they work.
Someone asked me recently if I planned on getting a new car. I asked them why I should? The purpose of a car is to get me from here to there and back again and my 95 Saturn does it quite well, both reliably and comfortably.
As for the snow blower problem and 8 inches of snow; move. That's what I did. I lived in CO many years ago for a winter and a half. The second time I had to prob for my car with a broom handle, I moved. Now I don't need a snow blower at all!
