In the beginning of this year I had taken up the acoustic bass. Only to find out it would take me more time (life is so short!) to get used to the physical challenges in handling this 1/2 sized beast of an instrument than I care to invest in. So to me my perfect solution is the one I have found in the NS Design cello bass!
The video demo on this instrument is the perfect example of where I am at. I am just not as good as the guy though!
