I personally have had no success with heavy dough with a home mixer.
They just don't have the horsepower or the gearing to withstand it for
long.

Here in the US you can find used but very good Hobart 20 quart mixers
for just over $1000 or so. Older ones can go for less, but they are
made for pro use and last forever, so they hold their value well.

You might find a good ugly one. If it works well, you can clean and
paint it and Bob's your uncle.

Good luck!
