I agree with Erin in that it will be difficult to rig on $3k. But you don't have to start with the latest and greatest stuff. Think about whats the most important to you and start there. For me it would be get the troller you want and add nicer electronics as the budget allows. It is a great time in a fisherman's life when they can rig the new ride. Enjoy your journey thru this. In my 50 years of doing this I have found the upgrades never end.
