I was with Equine and Livestock* and I paid £7.95/month to insure £1000 worth of bike and equipment. They paid out after 8 weeks costing £59 excess after I'd only been paying in 10 months.
They were also really accessible by phone, and if I hadn't done something (like dot the i, cross the t, or simply just kept in touch with how I was going in my quest for a copy of my crime report) they actually got in touch with me to see how things were progressing.
Quite impressed.
*not just for horse saddles, y'know!
