One of the best there are May 9, 2015

It's a shame that Omega discontinued this machine. Long twin gears, heavy, heavy motor (base), the whole unit is built like a tank. Furhthermore, it has the filter fully built in metal (seems to be stainless free), and the most important, easy to assemble, easy to clean with few parts. For the price I have found it (used) it was more than a... well... steal, sort of, since the seller did not intend to use it anyway.
Omega has come out just recently with the Omega TWN30S, however, the gears at this old model seem to be considerably longer...
