I don't like to see brands knocked when it's just because they don't happen to be favorites in one place or another. I don't have experience with Cordoba, so really can't comment on the quality other than I have heard reports from owners who seem happy with them. I do have a couple of Oscar Schmidt ukes...first the 8-string tenor, which is a laminate uke and a great bargain. At around $100, the usual reaction is that people can't believe the price is so low, and a very competent musician I know bought one right after trying mine, and is thrilled with it. It never needed a setup, it came with decent string height and good intonation, and is a great player. My other Oscar is a bit pricier, an all-solid quarter-sawn mahogany tenor with beautiful wood, binding, and gloss finish. After most of a year it's in perfect condition, no wavy top or back, perfectly straight neck and even frets, with nice tone and sustain that seems to improve as time goes by; perhaps no better than some of the other brands or models recommended 'instead', but it's a fine uke and they're in the $250 price range. It was not set up by the seller, yet the intonation is absolutely spot on, and I've never had to touch the saddle or nut because there's nothing to improve on, all the way up the fretboard. If anything serious happens, it has a lifetime warranty. I don't know if all of their models come so well-set up, but neither of the ones I own have needed setup, and they don't have anything else to apologize for.
If you can't find the model or brand you're looking for through the 'approved' vendors, as was mentioned earlier, you can buy anywhere and learn to do it yourself, or just take it in if it turns out it needs a setup. Many will, but neither of the two Oscars I have did.
