How to choose the best general synthesizers
Sound Quality
It's the obvious one, but at this price, we're talking about compromises. Expect a lot of digital grit, limited dynamic range, and sometimes a narrow sweet spot for usable sounds. We're looking for something with a hint of character, even if it's a little rough around the edges.
Polyphony
Most of these are going to be limited to 2 or 4 voices. That's fine for pads and basslines, but forget about playing complex chords with full voicings. It's a limitation, but a common one at this price point.
Ease of Use
A confusing interface is a killer. We're looking for synths that are relatively intuitive to program, even if the parameter range is limited. A few simple knobs and a clear layout go a long way.
Build Quality
Plastic is the name of the game here. Don't expect robust construction or rock-solid keys. These are toys, and they'll feel like it. But we're looking for something that won't fall apart after a few gigs.
Connectivity
MIDI in/out is a must. A headphone jack is a huge bonus. Audio outputs are essential, even if they're just basic 1/4" jacks. The more ways you can integrate it into your setup, the more useful it will be.
Buying guide
Alright, let's be real - finding a decent general-purpose synth for under $50 is a challenge. You're not going to get a Jupiter-8 clone, that's just not happening. But you can snag something that'll get you started, add some interesting textures, or just be a fun toy for sketching out ideas. We're talking about the absolute bottom rung of the synth world here, so manage your expectations accordingly.
At this price, you're buying a concept, not a masterpiece. Don't expect pristine audio or a huge range of sounds. Look for something with a unique character or a simple workflow that suits your needs.
Used is your friend - you'll often find better deals on slightly older models. Be prepared to tweak and experiment to get the most out of it - these synths often require some serious massaging to sound decent.

Questions
Are these synths any good for recording?
They can be, but you'll need to be very selective. Layering sounds and careful EQ are your friends. Don't expect them to replace a high-end synth for critical tracks, but they can add interesting textures and FX.
Can I use these synths with my DAW?
Absolutely! MIDI connectivity is usually included. You'll likely need a USB-to-MIDI interface, but those are cheap as well.
What kind of sounds can I expect to get?
Mostly digital sounds - think basic FM tones, square waves, and sawtooth waves. Don't expect realistic emulations of vintage analog synths. Think lo-fi textures, quirky effects, and some usable basslines.
Will these synths be loud enough to gig with?
Probably not on their own. These are best used with an external amplifier or as part of a layered sound. The built-in speakers (if they even have them) are usually pretty weak.
Are there any hidden downsides I should be aware of?
The keys are often unweighted and can feel cheap. The sound can be noisy - be prepared to deal with hiss and aliasing. And don't expect long sustain - these are often limited by their internal architecture.
