whew! i use the inexpensive MX-P50M w/my Duo, along with an LDG Z11... 2W in gives ~40W out, depending on band... autotunes nicely thanks to Z11's 60W max, but alas, no auto bandswitching

i like that everything is compact and works well w/my lightweight 12Ah lifo

that hardrock looks pretty though...
