I would say the from a money standpoint, the Trinity is the best deal. It's going for about $1500 right now and is really a great deal. The 61 key is still in production right now along with all expansions. I think what has made it so popular is the cleanliness of the sounds. The acoustic guitar is wonderful. The strings are great and its effects are right there with the Triton. If you totally deck out a Trinity with SCSI/Flashrom/Moss Board exp. you will basically have a Triton, just without the Sampler. I think it works great as a standalone synth. It has a touchscreen and doesn't have all the pages to turn through. I know it may have seemed a little expensive a few years back, but you have to try it out for yourself. As for the limited polyphony, I think sound quality makes up for this. Remember, sometimes less is more!!!
