Don't worry... I won't tell the people who spend $10,000 on ProPhoto lighting equipment.
BTW... hundred bucks for a lens? That won't get you too far up the chain of quality either. Lenses today are 4 digits for the "good ones". The current top of the line battery powered strobe is the SB-900 at just around $500.
Depends on what you want to do... a cheap flash is just that... a cheap flash, just like a cheap lens is just that.
Even one of the better bargains out there are the Vivitars and SunPacks that go between 80-150. A hundred bucks for a strobe is nothing incredible in terms of an investment.
