We recently purchased a Kohler Wellworth toilet and it worked so well, we purchased a second. It has a decent flush (considering it is a 1.6 gallon flush toilet), and if you find you do need a larger flush, all you need to do is hold down the handle when you flush to get the entire tanks worth of water. We purchased the entire unit at Lowes for $100 and so far are very happy with our new toilets.
