I had a policy with JLT for 1M for about 3 years, last renewal was £60 (ish) - my only concern was when I specifically asked them if they covered Laser shows and was told yes.. but I don't really believe them.. it was never a satisfactory answer and it's not in the policy wording.
I cancelled as I wasn't doing any shows anyway, but when I manage to assemble my hordes of laser modules and equipment into working projectors and manage to persuade local venues that I'm better than a £30 p/n Lasercrab I'll be in the market again.. just not with JLT.
