If you can afford to look at the xray, the a800 isnt' too far off and arguably the better deal as you really don't need to buy any tuning bits when you buy an awsomatix.
I love my xray and it has been very easy to drive fast, easy to work on, and doesn't go through parts too often. i've prob spent $100 in replacement parts for it since i got it in march 2016 and it has been a great car.
If i was buying another tc now id prob look at the associated from your list. they have made great progress on their car over the years and apparently the new car has the same plastics as their new line of buggies which is great news.
