Axial is probably the best crawler to get into for first time scale builders.
I would strongly Suggest a first time user to get a RTR, upgrade from there.
Im running a dingo kit. Rc crawling can get expensive fast, I have about $850 in my scx-10, $750 in my MRC, $450 in my Micro Crawler.
Rpp Hobby is an excellent website to buy from, spent several hundred with them and never had any complaints, always fast shipping to boot.
rc4wd has great selection, require packages to be signed for, often more expensive. but they have alot of unique stuff that's hard to find elsewhere.
