I have seen them in the $550 mark sometimes on ebay. I can tell you that at the $550 mark it is good value. Too me it is not so much, which one is cheaper, and more about which one will provide good value. Just the fact alone that you use a standard RC radio on a Tamiya tank sets you up for success.

I can tell you I am not a Tamiya guy and only have two Tamiya tanks and the rest are HL. The HL Sherman and the Panther are both decent runners out of the box. I would suggest you get a 4 shaft gearbox to improve the performance as the first upgrade. Stay away from all other upgrades until you figure out where you wan this tank hobby to take you,and as Gary has mentioned play around with that for awhile and see what you think.

Having said that a built Tamiya Tiger holds its value, and chances are if you want to unload it you can get a decent amount of the money you spent back, if you choose this hobby is not for you..
