Before everyone jumps on the SA "OMEGA" was/is no good bandwagon, some home work needs to be done. I'm not saying that the other pistols mentioned are not great or viable alternatives, but rather just defending the 'true' option of an OMEGA if that's what he's interested in.
Here is a thread from another forum with some excellent information on the OMEGA, and while there were some definite quality/function issues with the "earlier model year", those issues were worked out in the middle and later years.

You can find fault in many other pistols as well, like early Colt Delta frames cracking, or any host of other 1911 models with some issue or another. Many guns have had a rocky beginning. In all honesty my first experience with 10mm was an S&W 1006 when they 'first came out'. It was an affordable alternative at the time to the OMEGA, and the mostly unavailable Bren Ten which has always eluded my pocket book. Anyway, (I swear this is the truth) from the second round fired (factory ammo, not reloads) that 1006 locked up during extraction.. I mean serious 'take apart, dowel through barrel', etc... Long story short, I drove to Ahlmans gun store and repair, (authorized S&W repair) 75 miles from my house, (southern Minnesota) and the smith tested it, and agreed something was wrong. Anyway, got it back a couple weeks later, same thing.. Moral or the story, I would have never believed a S&W could have been like that, but I did get one, and was leary ever since. I know it's dumb, because there's tens of thousands that are not defective.. Just my experience.
The true demise of the SA OMEGA was more business related issues with the Peters Stahl company (in Germany)on importation and patent of the slide (which PS made and SA imported at the time), and the fact that it was a very expensive gun for the times. It's a shame they stopped making them just as the bugs were all worked out. I was lucky enough to get a like new used one late last year on GunBroker. I checked the S/N with SA, and was pleased to find out it was one of the last couple of batches mine was made in before they stopped producing them. All the issues had been addressed, and short of a possible lemon, I should have no problem. They were right, it is like a dream gun to handle and shoot.
So if you want an OMEGA, it is possible to find a good one. They are not all bad. It's like the news.. you just hear about the bad ones.. Read that thread I linked to, and just do your homework looking for a later one. They are out there. Here's the kicker... the downside is that there are no spare parts, and the guns usually bring in a premium.
Here is the one I got, and it's a tack driving cannon:
