We reuse old parts for the practice bot. The Comp bot gets new motors. So much of the cost is already sunk. If not a new control system is about $1500-2000 if you go out & buy it. The chassis is about $500-$1000 assuming nothing exotic. Then you have the mechanisms.

But you also have spares for competition. Keeping in mind the weight restriction for spare at competition.
