The OXK is made from synthetic materials (basically a special version of Formica). I don't think Ohana uses any synthetics, so they probably don't have anything comparable.
I have the Famous FS-5G (geared) and it's a great uke. Great for the money. Not indestructible though like the OXK. The FS-5G is super lightweight. The OXK is more like a tank. They're both great though.
The price point is pretty universal. But, I bought mine on Black Friday with a store-wide percent off coupon. Black Friday can also wrap around to Cyber Monday etc. in the States and that time frame is around the last Thursday to the last Monday in November.
Some vendors show the OXK at the manufacturers suggested list price and then mark it down to $279. Some just start at that price or call it a special purchase, So, a percentage off coupon may not be applicable on the OXK with every vendor even if they offer one.
The holiday season is a good time to pick up any ukulele or ukulele related item because of special deals or bundles - except for the fact that the intent is that you are buying gifts for others
Considering the quality of the OXK I don't think it's unreasonably priced. Yes its more expensive than a lot of other laminates but it's also a cut above all the other laminates I've played (I haven't handled a kiwaya/famous). I did get mine gently used for a good price. It's not totally a tank. My kids managed to split the binding on mine, although after I repaired it you can't tell it happened. It mostly sits in a hard case in the closet now.
Places like Sweetwater, Musicians Friends, Alto Music, and others who are Martin dealers all offer some sort of 0% financing if you want to spend your purchase out over time and not paying any extra in interest.
Sweetwater has 24 months 0% financing and I believe they still will price match lower advertised prices too. I bought a '59 Reissue Gibson Les Paul that way from Sweetwater a few years back.
If they will sell it to you for $279.00 that's only $11.63 a month with their free 24 month financing. Food for thought....
