Ukuleles Under $50
The next step up from the cheapest ukuleles is a step well worth making. Even in this price range, there are some nice instruments to be found.
One brand worth looking out for is Makala. These ukes are the budget line made by Kala and are one of the best buys if you're on a low budget. They come in the standard soprano (MK-S) and pineapple shape (MK-P). They've also hopped on the pink-ukulele bandwagon with their MK-SPK which features a dolphin shaped bridge.
On the other side of the spectrum are Morelli ukuleles (also sold under the name Santini). Before you buy one of them, be sure to read what I've said about them.
