My brother got into fly fishing with the above mentioned $19 Shakespere combo from Wal-Mart. Is it perfect? No. Will it break? Probably. BUT does it work? YES. I borrowed a couple different combos before I decided to buy mine. BPS runs their White River combos 20% off from time to time. That's when I got my Indian Point outfit for $59. IMO, it's as good as it gets. But for crappie fishing you don't need all the bells and whistles you might want for trout. Once again IMO, buy any combo you want, get a good tippet (5lb, 7ft = $3), and invest the rest in your jigs. Academy Sports & Outdoors has two different options at $39, both of which look good.
