I have classic car insurance with AARP insurance which actually goes through The Hartford. Good rates and no problems so far. They do agree value as well.
Yes....try reusing what you have to save on money..or if investing a lot then go for quality products....i made a big blunder while doing this purchasing cheap products :)
Craigslist always has some good ones available going at bargain rates, but the pain lies in waiting patiently to complete your collection. I keep waiting for good Gladiators to pop up.
I would call my home insurance company. Frozen ice related damage in usually covered under a standard home insurance policy. The worst case will be they find a technical defect and refuse to fix it. No harm in taking a chance if it saves you the time, effort and money.
