+1 on the Mantis as well. Fact is, it's $335 street in the USA, has excellent current output from its P/S, and is lightweight for portability. You can even get a matching gig bag for it, and if you feel the need to expand it, just get the expander links that match the cases. This would also make it easier to use some of the larger modules from the first build above, although I think you should try to keep the "panel bloat" to a minimum.
