Insurance can be an issue. I had my stuff through renter's (and later home owner's) insurance through State Farm and when I got it set up I explained what I was doing, so I thought I was covered. When a MIDI pedal blew up (and I discovered it was covered), they decided not to cover me any more. For the past 4 years or so, I have been covered by Heritage Insurance who specialize in covering musicians. Luckily, I haven't had to make any claims, but it's not too pricey and given the amount of traveling and playing out I do, I can't see not doing it.
