Well I ran both MMM and Tekin and both are awesome. Tekin, like MMM had problems with their first few batches of motors but fixed them and new cases are rare or due to someone being sold old stock. The MMM 2200 truggy motor is one of the best reliability and power for the money you can get. On a hot day dont let the fan go out, and you surely wont get 20 to 30 min of battery pack unless its HUGE. and they have been known to blow out their front bearing. Castle wont sell you a replacement but instead have you send it in to get a new motor. I'm waiting on my 2nd blow out replacement at the moment.
The Tekin 2000kv Truggy motor will be alot better efficiency wise and run cooler with its higher capacity ESC. Its more for racing and has on board tuning features, sensored and its own temp gauge that makes it very user friendly. Costs more but you get more as well as more motor options.
Pinion testing with your drive style will help get max run time too. Its increadable what 1 tooth will do sometimes. due to the difficulty of changing pinons and adjusting the mess with the RC monster motor mount I used to just "settle" with an all around gear. For that reason I like the Elite RC mount that allows me to change a pinion under super fast, to really let me tune for the very different tracks I swap around between in my area.

Easy to change bearings, motors, clean things & adjust gear mesh, plus the added bearing (same type as nitro clutch bearing) helps take alot of the load off the main bearing and shield it from dirt. Again it costs more than the RC monster mount but you get what you pay for and if money is not an object for quality then... well you know. I spent way more money trying to be cheap only to get the good stuff later, I sorta wish I had your approach or knew better when I got my 1st stuff.
Oh if you do get the Elite mount put a note that Jason Wipf plugged you into his product and I know he will move you up the priority list if he is tight on supply as that is a popular mount.
