The main components of a high end semicommercial machine are present...heat exchanger, good sized copper boiler, powerful vibe pump, autolevel, etc. all in a relatively inexpensive package (very inexpensive when purchased used, as I did). Probably the smallest heat exchanger machine on the market, so it is great for tight spaces.

Some of the bells and whistles are lacking - gauges, stainless side panels, a hot water tap, a decent sized reservoir, a commercial portafilter.

The Ellimatic (now discontinued and replaced by the Oscar) fills a niche at the low end of the heat exchanger market. Even when new, it sold for a couple of hundred dollars less than the Livia. What do you give up for this savings? In some key respects, not much...the boilers are about the same size, the pump is the same, the heating elements draw the same amount of power, the grouphead design is similar. But you do give up some features....first of all, cosmetically, the Ellimatic is pleasant but not stunning...its side panels are plastic (and prone to breakage during shipment) and not as nice as stainless (though perhaps easier to maintain, as they do not show fingerprints.   There is no hot water tap (fine with me as I have a separate Instant-Hot, though this also makes replacing the boiler water difficult).   Ther are no pressure gauges (but the pump pressure is not adjustable anyway, and the pressurestat can be adjusted according to the brew temperature). The reservoir is tiny and must be refilled frequently. The stock baskets are very shallow and the stock portafilter is also shallow and will not take deeper baskets (an apparent effort to maintain cup clearance). Still, this is a real heat exchanger machine that can brew and steam  in a league with Livia. A machine like this, needless to say, requires a good grinder and I have paired the Elli with a Rossi RR45 grinder.

Bought my machine locally from an eBay seller. Machine had been used in his former restaurant and was in good condition except for cleaning.
