I know this an old post, but im new to lipo and am going through the posts for info.
Can i just second the advice on not listening to the LHS guys, ive wasted more money from bad advice than i care to remember (probably enough for a good complete set up [:@]). Take the time to look around here (other good forums also available

) At least we can asume the people here are at least flying - For all i know the LHS guy might just be there for there pay packet!!!. and ask no matter how dumb you think you sound - we all began somewhere and have had the same problems. I totally recommend research and online purchasing but ONLY when you know what you want.
Sorry LHS
Allthough i do love looking around them and seeing stuff in the "flesh"
my 0.02p's worth
