Brushed Engines...

So I've been researching brushed engine upgrades, and have narrowed my options down to about 3 different engines.   First let me start off by explaining why I'm looking at brushed motors instead of brushless motors.  The primary reason is that I don't want to have to upgrade the ESC/Reciever/Servo just yet, but also it wouldn't be as much fun to just throw money at it and install a caste creations sidewinder and build the fastest car I can....that would get boring pretty quick.  I'm hoping to drag out the improvement process and also learn about how the gear ratios, timing, etc impact the performance of the Mini-T.

So now that I've got all that out of the way, I think these are the 3 best options I have:

• Venom Fireball 370p, ~$8 - This motor seems to be the cheapest option for increased speed, however it seems as though its hit or miss whether you get a quiality motor, and I've also read folks complain that they don't last very long.

• RX-280, ~$15 - This motor is recommended very often, and was actually recommended to my by one of the Horizon employees over the phone.  It seems that this motor adds significant performance increases while only giving you the option of replacing the brushes in the event that they wear out,.  Sadly, it doesn't seem that you can adjust the timing on this motor.

• Reedy Stump Puller, ~$35 - This motor also seems to be used as much as the RX-280 and is highly recommended.  It adds significant performance increases but is also rebuildable, and you can adjust the timings.

I should point out that I have not yet tested any of these motors, I'm just documenting my research so I can keep them straight.   Currently I'm thinking that I will go for the RX-280 and use it for some time until I eventually move to a Reedy Stump Puller to learn about rebuilding motors.
