I run the Jammin CRT Pro with an OS .30 and Hitec Digital Servos.... I don't recall the model numbers off the top of my head. I think it is a great all around racer. The new CRT 2 is out now as well... supposed to be a great truck.
Your going to get 50 different opinions here. It's like Ford vs. Chevy. Everyone's going to have their favorite. My advice is to read up in this forum on the subject. There are some great threads here for all the different Truggies out there. Also you may want to look at getting a truck that your LHS stocks parts for, so you are not waiting on parts to come in the mail.
All the trucks you listed are great trucks, and each one has it's good and bad points. It is ultimately up to you to decide what truck will best fit your needs, style, and budget.
Happy shopping and if you have any questions please don't hesitate to ask.
