We had the original Pegasus a number of years ago. Loved it. Also owned a Wersi Spectra at the time and played side by side you could not tell which was which. Never played or saw a Wing or OAX-1 but I assume the same can be said about those two? 99% the same internals. Based on that not sure what they would base a less expensive model on since OAX is the current O/S in their line up?
