beautiful day in MY neighborhood
I use an inexpensive (around $200--300) Sentry fire-proof safe.
Hard enough to open to deter the wankers.
Heavy enough to slow down at least a pair-needed wankers.
Can be bolted down.
Sufficient fire protection ('cause it'll either be enough, or nothing will be enough).
Mine has a combination dial....I think I paid about $200 in 1994.
