The ST is just one of the solid tops the one listed above is solid mahogaheny top. comes with a excellant case. the one marked at Hawaii music by phil are the ka t not st so probably not solid tops so they would be a bit cheaper. Looked for an ST as I would recomend the kala but didn't find one at other than a couple of the big stores. I recently bought a ka-s from hawaii music and they did a fine job setting it up. Amazing really for such an inexpensive uke. One of the other solid top kala's from there would fill your bill but come at a higher cost. The package deals on your first one will usually save you a bit as you need tuner case etc.
