Please don't order a uke from Amazon unless you (or somebody you know) can do a proper setup. The cheaper the uke, the more important it is to buy from a vendor who checks each and every uke, sends back the ones that are poorly built (factories are inconsistent) and tweaks the action so your uke plays in tune and is comfortable to play.
There are lots of threads here on UU about vendors who do good setups. Off the top of my head I can name Mim's Ukes, Uke Republic, Hawaii Music Supply and Elderly Instruments. They will not sell you a piece of junk.
Amazon sold me junk earlier this year. The price was $60 and I figured what could go wrong with a plastic uke? Well, I received a mint-condition shipping box and a uke with a broken bridge, shattered into tiny shards of cheap brittle plastic. I sent it back (Amazon gave me a refund, no complaints there) and I chalked it up as a reminder that conventional advice -- buy from vendors who do setup, you get what you pay for -- is generally correct.
A $120 uke that you enjoy playing is a far, far better bargain than a $60 uke that's unplayable.
