Got the Savage X good truck can take a royal beating. Yet to brake a part on mine. The RTR has the F4.6 which is a damn good engine.
BTW that ebay one is a rip off that you said in your other thread
http://www3.towerhobbies.com/cgi-bin...=LXRYP0**&P=ML $404 RTR from a hobby shop enter cupon code 016D8 for $20 off (should be about what UPS ground shipping costs)
Only thing about it is the manufacturer settings for break in are too rich and the needles usually have to be leaned out a bit to be able to hit proper breakin temps.
The XL is a few inches longer and a tad bit wider and has a bigger engine. The X is the better deal though you can buy the XL plates arms and dogbones for like $45 and buy a good engine for the price of the XL (the K series engine are not that good that is in the XL and X SS, The RTR though has the F4.6 like i said above)
also I would recommend 2 parts for any savage the RPM skid plate

and tank guard

hope that helps
