I was in the same boat as you about a year ago.
I tried a JS100 (had been looking at SG's, SC420's and others) after some guy in Sound Control said "hey, have u tried one of these.."
Well, I think even the JS100 sounds really nice, very versatile, but I'm still not very skilled at trem abuse so for my purposes I guess even the LoTRSII would be fine.. but..
I saved up, borrowed a little off my parents, and got myself a JS1000 BTB
I was reading up on them online, I really wanted a BP model and almost got the JS900 but at the last minute realised that the 900 is missing most of the features I wanted!
well that almost ruined the whole thing (price getting too high) but I spoke to CodaMusic and they gave me an amazing deal on the JS1000 - cheaper than the JS900 in Sound Control!
So here I am a year later, knowing I made the right choice
Wait for a JS1000.
