If you want to get your toes wet with studio strobes you most likely don’t want to break your bank account. This is especially true if you are on a budget. But this shouldn’t withhold you from getting started either.
You can start your studio strobe adventure with gear around the $100,- per strobe and this will be enough for now. I always suggest to get to the edge with the gear you have before you upgrade and go to the next level. At least this is my upgrade strategy.
