Liberty Mutual
We were State Farm and the cost per sled for full coverage was approx 220 per sled State Farm in IL goes by CC's not Horsepower, so when we went to Four Strokes they really wanted to shoot up the cost.
I shopped around, and found that I could (now I get a discount of 10% through my employer) get full coverage for FOUR sleds (97 XCR 600, 99 XCR 440, 2005 Vector, 2006 FST) for 268 per year. Yes thats right all 4 sleds one price. (100 dollar deductible, the rest is all standard).
I had to switch the house and the cars (cars were cheaper than State Farm by 30%) the house was a bit more expensive than previous, but I did add sump pump failure insurance).
Liberty takes out monthly for all insurances in one sweep, and does not charge extra to go monthly, in fact, it seems its there preferred method of Payment. My brother in law just had a self induced flood in his basement, forgot to turn off the water outside, and had a good experience with his claim.
All in all, glad I made the switch, saved quite a bit of money.
