IMO if you plan on using outdoors, i would shy away from Micro scale, TRX4m, redcat ascent 18 and scx24 are relatively all close to the same size. all around 6" wheelbase.
yes they are cheap but they are small enough were i find them hard to enjoy unless restricted to a specific spot, then carry to the next spot. it might just be the terrain around where i am, but always feels like a chore just getting from point A to point B without getting stuck on small rocks and gravel a million times. fun at first then the shiny wore off, for me at least.
Whereas with 1/10 you can run at a spot, then drive to the next spot more easily. or even just taking it for a walk lol.
i would stick to the more known brands, Axial, Redcat, Element (Team Associated), etc. if you have a hobby shop local, i would get a brand they carry and have parts for, if not the above brands are some of the best. Traxxas is OK, but they are high in cost for what you get compared to Axial/Redcat offerings, that and i can't stand them as a company.
crawlers are also very modular, you dont really "need" a whole lot mostly preferences that will be aquired after running them, but what you do find you need after learning them, you can upgrade to incorporate it. i would highly recommend getting a good hex wrench set for the majority of sizes you will need. standard "L" keys wear out quite quickly and can start causing more headaches and cost due to stripped/ruined parts.
something like in the link below is what i use alongside my machined driver kit, and has done me quite well.
