ditto what skate said,but ill throw my 2 cents in.i think that all the major manufacturers make quality products.im sure people will have stories about having problems at one time or another and having problems with customer service,but overall,i feel they all are quality products.i feel that first off you need to know what your budget is.that will determine where to start,next you need to know what features you want,like dual frequency,bottom zoom,bottom lock,what type of transducer,ect.another important thing is the size of the unit,in the case of electronics i feel that bigger is better,but how much room do you have to mount it.once you know exactly what you want,do some shopping,i bought a new si-tex last winter,i was patient and did alot of searching and the one i bought i got for 100 bucks less than anywhere else.oh,and by the way,i love my si-tex f.f. and just bought a si-tex gps to match.good luck!!!!
