Re: Should I consider a JS-100 as a backup for my JS-1000?
The Js100 is a very different guitar -- different neck, cheap bridge, cheap pickups. IMHO, the JS100 is too overpriced for what it provides. If inexpensive is the concern, you would do better with a different model that is cheaper and with better hardware. Maybe something like a used S540 with an Edge and decent pickups (but a very different neck shape). I wouldn't rule out a used, player-condition JS1000 as a backup either.
If security is the problem, you need to lock your stuff up, don't leave it unattended, and get some insurance. Getting cheap gear seems like the wrong solution.
That said, if you can find a used JS100 for a good enough price (factoring in the cost of a pickup change), it may be worth going for. Go play one in a store for a while and see whether you would be happy with it or not. It's not a 'bad' guitar if you can get it for the right price.
