Need a project - Maybe M-LST? (Need opinions)

[BP-Revo]

Well, I'm most likely going to get my 18T sold soon, since its just too small (low) for where I run.

I'm looking for a new project, in which the vehicle will replace the 18T. Of course, I want it brushless. I'm basically looking for an electric I can run when I don't want to run something as large as the G2R and something to run when the G2R is down. I have enough Nitro's (T-Maxx, Revo 2.5R, Jato 2.5), but I only run nitro in large duration, like over an hour, and usually for bashing.

Anyway, I'm looking for a semi-easy build, and hoping to keep it below $600 or so. I already have a radio/receiver for it, so that won't eat up any of the funds. If its a really good project, I may splurge as much as $750 or so, but I think thats the max. Any more than that and my parent's will raise an eyebrow (technically not supposed to spend anymore on R/C, but I get leeway for selling the 18T). I would like 4wd as well.

As of now, I'm looking at the Mini-LST. I have taken pretty detailed looks at them and they look pretty cool. They have pretty good ground clearance so I can get around where I need to. Of course, I would get the standard upgrades like viscous diffs, CF chassis, etc. I was also planning of running 2.2 inch truck wheels and tires (if possible - I think it is). If I was to get this thing, I was planning of putting a LMT 1525/6 in it. I am going to run it off 2S, 5500mah Lipo (the maxamps saddle pack, since it would fit perfectly in the rear with few mods, according to the dimentions). For the ESC, I dont think the Mamba 25 could handle it (can anyone comment on this?) so I was going to actually take it overboard and run a MM (what I'll do is run an MM on my G2R, then when the MMM comes out the MM when go to the MLST). Anyone thing a LMT 1525 is a bit much?

Anyways, I'm just looking for opinions in general. If anyone has any comments on the MLST plan or thinks that another truck would fit my needs better, go ahead and throw it out there.
