kelly, i'd advise you to grab either of the 2 is40's on ebay now closing tonight..i've used the is35(same but w/harmonizer/input)for 7 yrs and they( i have 2) are built well and have been trouble free. i have owned and tried many others and NOTHING is as well laid out and makes as much sense for live navigation as these units..sounds are easy to modify. i have rarely seen them up for sale, let alone 2 at the same time..don't let them get away if in your price bracket, unless you need features that newer kb's have that these don't..for the money..they are a super unit.
