1-1.5k won't be enough if you are looking for a good set.
My suggestion is:
1. Get a good radio (sanwa or futaba - easily 600++)
2. Get a good esc and motor (easily 400++)
3. Get a good servo (savox etc 200+)
4. Get a medium range chassis (about 400++)
5. Battery also cost quite a bit (budget 200)
as a beginner, I think start with a medium range chassis is better as parts are cheaper and u can afford bashing and crashing.
Item 1-3 worth investing more because ppl tends to upgrade if started with lower range stuff.
Myself already upgraded the radio from a cheap china make to futaba.
And change a couple servo already.
I can only advise EP. Not a nitro guy.
Just my 0.02
