Also, remember that the dolphin is plastic. That has advantages and disadvantages. You can spill things on it and you can get it in fun colors, but it doesn't look like a "serious" instrument. I'm personally not a fan of the plastic ukes because I really like wood. So, I'd pick between the MK-P and the MK-S. But the suggestion of looking at Mim's is a good idea. Here's what she says about an inexpensive Ohana:
My personal go-to uke is my SK-10. It is a blue one just like this one and was given to me as a gift and though I have access to hundreds of ukes, the SK-10 is the one I grab most often! I love it! The laminate makes for a very stable uke, so I can take it anywhere and I am not worried about variation in temperature or humidity effecting my uke. The construction, however, is so light that though it is a laminate uke, it is very resonant and has a nice full tone with good projection. It also has REALLY nice frets for a 'starter uke'. Then for fun, this uke comes in fun colors! So when people ask about what uke they should get to learn on, I always say they cant go wrong with an SK-10. The sound and intonation is spot on and helps the beginner uker to feel successful! And the yellow is the happiest of colors! Full of sunshine!
I sell these for a little more than other dealers, BUT... it is because I will set it up with Aquila strings. It gives this uke a nice punchy sound and a lot more volume. They also stretch less than the GHS string and therefore make this uke a lot more fun to play! I also take a lot of time to set up your uke to make sure your action is good and your frets are even and your uke is buzz free. I work just as much time on low-price ukes as I do high-price ukes. Every uke gets my personal attention.
Ohana offers unique and well-made ukuleles. It is a favorite brand in the ukulele community and is very well-respected! They have high quality standards. You are going to love your Ohana ukulele! If you have any questions, let me know!
Mass produced ukuleles come with "factory settings". There is no time to set the uke up for the individual buyer. Often they err on the side of high-action (strings are high over the fretboard) . I take personal time with each uke I sell. All ukes get a nut and saddle adjustment. They are also checked for fret buzzes, intonation problems, and other issues that can be resolved in the set-up process. The action is lowered to an ideal and comfortable level. You can feel the difference between a non-set up uke and a uke that has been through the "Mim Set Up Process". I have repeat customers world-wide because I have worked hard to have the reputation that a uke from Mim is going to be "right". The set-up process can cost a lot through your local luthier and often they do not know the specifics that go into a good uke set-up. I only sell ukuleles, so my set-ups are custom tailored to your uke, the brand of uke you purchase, and the uke size. If you need a uke set-up Low G, or Lefty, let me know. I can do that for you... no charge! I set up the uke for YOU the buyer and ukulele player!
She sells lots of Ohana's, and it is a business, but she's working to make even an inexpensive uke a great experience. So, if you're torn between a few options, and thinking of buying from her, shoot her a message.
Enjoy your new uke!
