Start with a basic fixed pitch one, cheaper the better. You will crash it, a lot.
Check out what they have in stock at Fields on Union, and sepecifically what they stock parts for. Heli’s are EXTREMELY fragile compared to planes so most little mistakes result in some small part being needed.
Once you get a little better you can toss the cheap fixed pitch and get something with collective pitch. It will fly better and be much more responsive, but be even more fragile because of all the little linkages that make up the collective pitch rotor head.
A good starter:
