Not sure then - if refined genetics (might be bagseed, but you know the strain) are going to hermie on you, and bagseed is supposed to hermie on you then no, I wouldn't bother growing anything and would stick to buying.
Still, hermie fears aside - you have the same choice: throw money into seeds you may very well kill, or bagseed it for a learning grow and spend the money on start-up equipment that will serve you past the learning phase.
I would probably go with an indica dominant strain at first though. Unless you have a lot of patience.
Just my opinion.
