What's Interesting In Espresso Machines?

I confess to being a little torn about which aspect of espresso equipment I should focus on next. There are a few individual machines that would be interesting, but there are some comparisons that would be interesting too. So I'd like to hear from you on this - if you fancy it then just let me know which of these would be the most interesting to you.

I can't guarantee that the winning choice will appear quickly (some will take a fair while to prep) but your insights and guidance are always valuable.
