I realize, this thread was asking for an immediate advice and is certainly not up-to-date anymore... anyway, for future reference, here my opinion:
As Jim already wrote, Bruekos are much more popular for their soprano and especially their longneck soprano models (soprano body with concert-size neck). At least, that what most people seem to like and have here in Germany (no empirical research done on this, just my personal impression).
But I do own a tenor-size Brueko and have played a couple of others as well. Their standard tenor model is indeed a concert-size body with a tenor neck. On top of that, the neck has only 12 frets, which seems to put off many people.
I think anybody thinking about buying a tenor Brueko should be aware of this to avoid a disappointment.
Brueko offers also a model-size they call "jumbo" (both with a concert neck or a tenor neck). This is closer to the usual tenor size from other builders. However, they hardly ever advertise this on their website. In any case, it is advisable to contact the Brueko guys before ordering something, as they usually have more instruments in stock than they advertise on their website.
But: Personally, I like them very much: Nice to play with plenty of space on the fretboard even for my bass-accustomed fingers. They still have the regular Brueko sound, which is rather harsh and percussive, something quite different from the regular Hawaiian mellow sound that many people expect from a ukulele.
Mine is a flat modell, with cedar top and rosedwood body, the body is about 3 cms flat. And banjo-ukes or resonator ukes aside, this is by far the loudest uke I have ever come across. And by "loud", I don't mean "loud for a ukulele" but LOUD. Jamming with a guitar player? No problem at all. The cedar top and the flat rosewood body provide an incredible sound projection. It is certainly one of my favourite ukes, but not meant for any occasion.
On the other hand, I have played a couple of times the standard Brueko tenor, made of mahogany. It is certainly more concert-ish in sound than a "usual" tenor, with more sustain than a concert. As with the Brueko sound in general, it is something you have to get used to, I believe.
I also used to have a standard tenor-sized model (i.e. with a concert body) with a spruce top and a rosewood body I sold this one again, as it sounded quite thin and somewhat disappointing to my ears. Yet, I didn't experiment with different strings (what I should have done), and since selling it I realized that Aquila strings don't seem to sound well on any Brueko (at least, on any I have heard so far).
But then there are the newer tenor models with an arched back (as to the regular flat back), which seem to be fuller and richer in sound than those with a flat back.
In any case, I would strongly advice to get one of those with an arched back.
Just a feqw thoughts on tenor Bruekos. I hope this helps someone coming to a decision.
