OK, since Kabooms seem to be prevalent recently on the boards, can someone who really knows kaboom offer some guidance on the differences of the varying kaboom models numbers and where they stand in terms of release dates? Are some better or more reliable than others or are they all essentially the same? I know I looked up the remote on my RV-NB1 and it's like $50+ but the remotes for some other ones B or DP models are like $14.99. I also notice that some models seem to have lots of parts still listed while other models have very little parts listed. Just curious.
