If you want to buy a Tamiya body for $50 that will be heavy and will break after a few runs go ahead, you have that right. I'd rather spend $23 on a body and have it last 1-2 months. I don't really care about realism too much, as long as it's not butt ugly I'll run it. An attractive shot of paint can make even the crappiest bodies look good.
This is ground that has been covered many many times.......
