Good advice here, and thank you all for replying. Ah, the cheap instrument vs. the expensive one for beginners - I, too, would advise a new student to buy as fine an instrument as possible, but at the same time, it is a lot of bread to put down on something they may not like a bit. My first banjo was a professional model, just lovely in all aways, and I only touched it a few times (I had worked with a teacher who was a bluegrass guy, and that might not have helped much), and sold it for about a thousand dollar loss, just to be rid of it. Many years later, I got one someone had bought at a tag sale and badly restored, and after working on it a bit myself, I love the thing. High action still, but a sound instrument with good tone, if seriously ugly to look at still.
Renting is a good option, and I live in Western MA, so there is a concertina store in Amherst, near me. Honestly, the idea of putting down 4,000 for a vintage instrument makes my hair stand on end, although I also know fine instruments never come cheap, and the best you can get is always the way to go.
To answer the question of high vs. low, probably a tenor model would suit me, although a higher one might be fine too. A lower one might be nice, too. You see, I'm flexible. I sing bass, btw.
Sounds like the duet might be the way to go, as would be an English, though not a perfect solution. The Anglo seems to me that it is counterintuative, but I am not knocking those who like them. Just not for me.
Say, does anyone here use their instruments for something other than folk music? And would the sound of the concertina lend itself for more than folkie stuff? I've heard very few real live concertina players is why I am asking, and have yet to look into recording artists and all that.
