FWIW, as someone who had a 1981 4003 and a 1978 Univox Stereo Bass at the same time, they were both really great basses. I'd say just keep looking for both a real Ric and a good 70s MIJ copy, and whichever one comes up first at a good deal, snag it. You can always resell.
As for regretting having a copy, I see no reason for regret. I had a copy, got a Ric, liked the Ric a little better, sold the copy. No problems here!
