Not to be snarky, but the people that actually know something about FG bikes are going to give you better advice than the kind of people who are going to buy the cheapest bike on the market. These bikes are ok, the frames are pretty good, the hubs are good but quality varies on the wheel build so you may have to do some truing. The stem, pedals, and cranks aren't awful, the bars are, and the tires are cheese whiz. The cog and lockring are junk, make sure they're installed well but you still might strip the hub.
Consensus is they're an ok way to get into FG bikes, but you put on real tires, a real cog and LR, and better bars and/or pedals and it's creeping up on the cost of an IRO, which comes with better wheels as well. If I bought one I would at least lay down the $35 for a cog and LR, you would probably want to to customize the gearing anyway.
