How to choose the best general synthesizers
Sound Quality
It's not going to be Moog, but does it have a usable sonic palette? We're looking for something beyond just cheesy presets - a little tweakability goes a long way.
Build Quality
Plastic cases and flimsy knobs are common at this price. We're assessing how well they'll survive a gig bag and a few years of use.
Playability
Keys feel, knob responsiveness, and overall ergonomics matter. A synth that's a pain to play isn't worth the price, no matter how cool the sounds.
Connectivity
MIDI in/out is a must. Audio outputs are crucial, even if they're just basic 1/4" jacks. Limited connectivity can seriously hamper your creative workflow.
Versatility
Can it do more than just one sound? A decent range of waveforms, envelopes, and effects (even simple ones) drastically increase its usefulness.
Buying guide
Look, you want synth sounds without emptying your bank account. It's totally doable, but you gotta be realistic. We're talking under $100 here - that's pawn shop prices, used market hunting, and sometimes, software emulations. Forget about lush analog filters and polyphony; we're chasing bang-for-the-buck, not pristine studio quality.
At this price point, compromises are inevitable. You'll likely be dealing with smaller polyphony (think duophonic or paraphonic), limited modulation options, and potentially a bit of noise. Don't expect deep, resonant filters; you're looking for serviceable sounds, not pristine recreations.
If you're serious about expanding your sound, consider a used rack module - they often offer more features than the cheapest keyboard synths.

Questions
Are there any good analog synths under $100?
Extremely rare. Most will be clones or very basic models. The used market is your best bet, but be prepared to do some digging and potentially deal with repairs.
What about software synths? Are there free or cheap VSTs that are better?
Absolutely. There are tons of excellent free VST synths that will blow away anything you can realistically find hardware-wise for under $100. But sometimes, the tactile feel of a knob is worth something.
I saw a vintage synth for $80 - is it a steal?
Probably not. Vintage gear often needs repairs and has quirks. Factor in potential repair costs - those old electrolytic capacitors aren't cheap to replace.
Can I connect this to my computer to record?
Most likely, yes. Look for MIDI ports and audio outputs. You'll need a basic audio interface on your computer, but those are relatively inexpensive too.
What's the deal with 'paraphonic'?
Basically, it can play a few notes at once, but it doesn't have true polyphony where each note has its own independent envelope and filter. It's a compromise, but it can still sound cool for pads and drones.
