good question..and one i pondered as well as i watched an auction on ebay a few weeks ago (turned out it went for more than i was willing to pay for it) but, i kept asking myself, why would a person go with an LM2 model versus the newer supposedly much improved LM3 version? so i searched the net trying to find the difference and aside from the housing etc..i found zero information to say why the LM3 is better. maybe someone can shed some light on this so you can get a more informed opinion (even the zodiac company website information didn't tell me what made the LM3 better)

maybe it isn't and it's simply prettier to look at?
