chuck, most major brands offer a "low end" finder that is tons better than the best units 10 years ago. The eagle fish mark 320 can be found for under $150 usually. Garmin has some great units out also, just avoid the 100, 120, 140 ones - they dont have enough pixels. I am particuarly fond of the 240's - they are a great unit, and you can track a grub down to about 40 feet - you can find them used for $50 - $125
