T4.1 is a great truck. and a good choice for a first vehicle. even better sense you and your dad already have some experience with the T4 and AE in general.
there are a few other stadium trucks out there. traxxas rustler, duratrax evader, hpi e-firestorm, and probably a few more i can't remember off the top of my head. my personal opinion is that the T4.1 is the best option. best handling, best parts support, from what iv seen durability is good, it's a more current up to date design, it might not be as fast out of the box as the others, but that's what aftermarket motors and ESC's are for. it's fully raceible if you ever want to get into racing.
the rustler is a good truck. but it's an old platform. it's fast in a straight line and it's durable, but that's about all it's got going for it.
the evader is a good entry level truck. it's based off (or should i say "is" ?) an old losi chassis so it handles well. it's pretty damn fast, is pretty durable and comes with the 1 year stress tech guarantee. if you brake the part they replace it free the first year. parts support is typically good.
the e-firestorm is probably the second best option you could go with. fast, durable, handles well, good parts support in most areas. it's good at everything, but not great at anything.
