I think my last 700 crash was about $500 to fix, and it was a really really minor low altitude dumb finger mistake and I hit throttle hold before it went in to minimize damage. The damage was rather minimal actually and didn't need a re-kit, but blades and parts sure add up fast, and I lucked out and didn't damage a $375 14S battery pack.
That didn't discourage me though, I doubled down on the stupidity and expensive crash costs and decided my electric 700s weren't enough financial risk in the air... So I built a turbine 700 that I do aerobatics and "light 3D" with. It's heavier and less powerful than my 700 electric, but sounds way cooler, lol.
Only close call I've had with it is when the clunk fuel lines in the tanks got hard after about 2 years and I didn't realize it, so they weren't able to move around freely and pick up fuel in all orientations. Turbine flamed out while inverted about 3 minutes before my normal low fuel warning; the transmitter started screaming "low EGT" and then "flameout" and then things in the air got really quiet... Managed a successful autorotation with no damage though.
After that close call I now change all the fuel lines once a year... Especially the clunk lines in the tanks.
Large RC aircraft of any kind are an excellent way to turn money into a collection of broken parts on the ground, lol. All it takes is one fat finger mistake or a little mechanical or electronics failure. Still fun though, paying crash costs not so much.
This reminds me, I haven't flown in a while now... Probably should put in some refresher sim time and take them back out to the field.
