The nice thing about Martin reels is you have plenty of choices. Any of the reels pictured below would likely meet your needs. From left to right starting with the top row are the Martin 60, 61, 62 and the Martin manufactured Browning Midas 1. On the bottom row are the 63, MG-3 and MG3SS.
The 60 is RHW only because it has a single cutout in the frame, but the other reels are all LHW capable. The 60 and 62 are smaller than the 61 and 63, but weigh about the same. The empty weight of my 60 is 3.7 oz vs 3.8 oz for my 61. The MG-3 and Browning badged reels feature the Martin helical spring click and pawl check, while the 60-63 have the caliper spring check. The helical spring reels are nicer, but they also go for more money on the secondary market. You can find a caliper click Martin in very good shape for very little money, and they are perfectly adequate for chasing sunfish, small bass and stocker trout.
