Well, that was 2 weeks ago. Maybe the guy got paid. I don't know what the situation was/is between you too but I can only speculate upon info that is handed to me. It should not be surprising that somebody doesn't have money one day but has plenty 2 weeks later.
As for which rig... you are all over the place man. Nitro, Electric, 1/10 scale, 1/16 scale. The only thing that seems to be certain is your budget. You really need to narrow this down. Otherwise, folks are just going to suggest the rigs THEY like rather than the rigs that might be right for you.
First things first...
- Nitro or Electric? I'm not going to start a debate because there are numerous threds on it. You need to decide what you want.
- Scale? How much space do you have to run. Smaller is cheaper, do you need to sacrifice size to get everything you want within your budget?
If you can at least let us know where you sway and WHY when it comes to those two questions then and only then will you get any real help.
