Chuck ...time to invest in an E3 and forget about these lesser brands :-)

Like the out-of-the-box Leica Ms that went up Everest and the 'blads that 
tootled around the Moon in 1969 why not stick to this list's favourite 
out-of-the-box brand ? -:)

jh

ps: You will get to upload some of the thousands of shots taken on your 
cross country trip?
