The costs is how you spend it with clear thinking....
You can get a Hudy full automated tire truer for 400 dollar, or get a cheap non-automatic for 100 euro's. Better maybe to go on the 2nd hand market or make one by your own. With starterboxes likewise, you can get a 200 euro set included 2 high power battery packs or get a airplaine startermotor with a rubber starting wheel, an acid 12v battery and build a box arround it for just 60 bucks.
True down the tires or train them to the right size.... A question you can ask to get more drivetime out of your tires without more costs.
A starter in the 8th scale onroad can buy a Collari package for 900 bucks or a R&B S7C with exhaust for just 300 bucks.
You can make it as crazy as you want but do not complain about the high costs.
Within electric racing it is a lot worser. Every year those guys have new powersupplies, high advanced chargers and dischargers while I for example at clubracing managed to become champion in stockclass with just a simple 5A charger and an old Kyosho TF4R chassis on 1 (!!) batterypack.
