Gotta disagree with you on the .46LA. Granted it (and the .40LA) are not powerhouses but they are not meant to be. On the other hand, they are very reliable engines.

I would include the OS .40 LA -- not that it is a really bad engine, but it is gutless & much too expensive for what you get. The .46 LA is the same size & weight ,but noticeably more powerfull & is only a bit more costly (although it too is not really much of a bargain).
