I'd totally go with the toys, if you're into action figures. At your age, I'm not sure you realize how long Indy fans went without action figures, or at least ones that were easy to find, so I'd take advantage of the plethora of Indy figures on the shelves now. Who knows how long they'll last? Of course, this might be the 9-year-old in me who never got to have Indy toys talking.
I would suggest this shortlist of figures based on what's now available:
Indiana Jones w/ removable hat from KotCS - This is a great figure; good likeness of Ford, good poseability, and nice accessories, including an extra hand holding a crystal skull that you can switch out with a regular hand.
Indiana Jones w/ horse - This is my favorite of the classic Indy figures. You can not only replicate the classic scene from Raiders where we jumps on the horse and goes after the Nazis, but it's a great figure in its own right. It's got a similar body to the Indy I mentioned above, as well as the poseability, but with a wider stance that looks very dynamic. The likeness is pretty good.
Irina Spalko - The sword-wielding Russian nemesis of Indy in the new movie. Nice figure, but like any figure in this line, try to find one with good paint applications. She comes with another (although larger) crystal skull as a hidden relic. The hidden relics each of the figures comes with are a very fun part of this line.
Mutt Williams w/jacket - This will give Irina someone to duel with. Despite not knowing the character yet, I really like this figure. And he comes with the Spear of Destiny, which is a great relic to send Indy after.
German soldier 2-pack - Jones is always going up against these guys! Good way to get two for a decent price.
Cemetery Warrior - Another badass villain for the good guys to fight. I don't know how awesome or not he is in the film, buy the toy is great. He's a little hard to find.
And if you don't mind having a third Indy figure, I would suggest getting the Indy with the Ark of the Covenant, just because the Ark is an awesome relic to have.
Hope that helps,
Kevin
