My best buddy has a 20 foot koffler with a 200 merc he has been guiding out of for 11 yrs and he just ordered a new one i have rode in it many times I am not sure the dollar cost compared to the others but i know it has been trouble free and has had no problem with any of koffelers workmanship I also know that diamond nback boats will custom build a sled for you and beat everyones price I bought one of his 17 ft drift boats and it has been the best rowing drift boat i have owned and about $2000 less then anyone else around so you might give the boat builders down here in eugene a look see
