AngelList is by far your best source of deal-flow.
The recent introduction of syndicates will increasingly force most investors investing under $100,000 per company to invest as part of syndicates (which charge a carry) on sought-after rounds but there are still many good quality companies where you can invest independently.
With or without AngelList, try and share deal-flow with other investors you like, respect and trust. Focus as much on building your network of fellow investors as entrepreneurs and makers.
Happy to talk to you more about AngelList and what I've seen and experienced there.
