I dont have one of the machines you are looking at, but have been having a little peek at them occasionally (one day... :-/).
Have you checked out this thread:
Where are you located? I would check out the site sponsors and drop in to have a look at some of these machines if you can. Chris Natoli (Talk Coffee) has both machines youve mentioned, as well as a lot of others you may consider (too many to mention but any in this price range worth a look at).
I myself would love a Unico Splendor (one day) - I note Chriss comment on the excellent build quality as opposed his comments on the Expobar (although there are many very happy Expobar owners). Anyway, give him a call.
And dont forget the grinder - essential you have a good one otherwise youre wasting your money on a HX machine.
