I am about to buy a Minn Kota SP I-Pilot trolling motor for my 18' Kenner center console and wanted to get your opinions on where to buy, or where to avoid, buying one online. I've searced my a$$ off and cannot find any big price differences on these. This model is $1,199 and the lowest new I've found it is $1,179. Buying online could save me taxes (I am in TX), but if I have problems, returns could be a pain. Any tips are appreciated. Thanks.
