If I had only bought things I really need I wouldn't have a DMM, scope, soldering kit, numerous fascinating bits and bobs, in fact I wouldn't be a small-time electronics hobbyist and I would have missed much of pleasurable interest. Dead men buy no new toys, that's my attitude to hobby purchases, especially when the sum involved is as meagre as $45.50. In other words; buy, learn, enjoy.
Everyone here knows exactly what you mean by reflow, I'm sure, so why anyone should be so sour as to pull you up on it is quite beyond me.
