If you are like me and looking at budget rigs, I am liking the RGT 136100v2 or the EX86010 for 1/10 scale right now. Both can be had RTR for like $75, seem tough enough and are a little slower than some others (which is good for my kids). From what I can tell, they seem to have pretty good parts support and all the reviews I have looked at make it look like a good fit for us. It's on my list to purchase when we have the money (kids are getting 1/24's axials for Christmas).
We have some 1/24 scalers and some WPL's so far and I am impressed with the RGT's the most. Really solid rigs from what I can see.
I will add that I am fairly new to this and definitely not an expert, but I do pride myself on finding the best deals for the best value.
