Take a look at the SHIMANO IX 1000R or 2000R reels. They are low cost and would make a good replacement for those little "baitcasters" you're talking about.
For as cheap as they are they last a long time and for trolling the rear drag is very handy. Monk(monkscrappie.com) gives a good price break if you buy 4 or more($11 each).
"WOW" hard to beat price on Shimano reels!!!! Thanks
