I would suggest getting the new 4x4 Stampede (although I have never seen one in person) as it is basically a 4x4 Slash but with more ground clearance and bigger tires for more traction. It is on the cheaper side of things compared to an E-Revo or Savage Flux but will still be fairly reliable and pretty fast with a 3s Lipo (11.1v). Whichever route you end up going I wish you the best of luck in this hobby and hope you have fun with it!
