dude, omg dude man thats sorry to here dude, i know how you feel, except in my case my truck was stolen.
anyways, you had the muggy so you pretty much had a lst2 except a few things such as reverse, 2speed, and high low gear.
i would get the savage man, i got both muggy and savage and my savage has taken some serious abuse that my muggy hasn't be able to, the 4.6 is a nice big block and easy to tune motor. the x 4.6 rtr does have a few bugs here or there but its the same with any new truck hence when the muggy came out it had its clutch problem... i love my savage. but if anything i would also look into the xl, it has a lot of fixed problems with the s 4.6, with the steal spur, roto start, better diff, 3 speed, etc...
one thing also to look at might be the new mgt 8.0, rcca just did a review on them and compared it ot the lst2 and it came out swinging, yes the lst2 is more out of the box race ready and takes very little to make it even better next to the mgt, but with the lst2 price and the mgt u would have some cash left over from the mgt.
but if i was you i would give the savage a try, and if you are up to it get the kit it will help your building skills its fun, and there's not a better felling then being able to look at what you built with your own hands, and you can save money by building it. all you need is a radio and 2 servo's
anyways if you want vids here these are some from my xss before and after the picco.
