Where to find cheaper 2-layer prototype PCB boards than h-instruments.ecrater.com?

The discussion centers on finding cheaper sources for 2-layer prototype PCBs compared to h-instruments.ecrater.com, which offers 5 pieces at $29.95 including shipping. Alternatives suggested include Chinese PCB fabricators known for low-cost prototyping with fast turnaround, such as pcbgeek.com, bittele.com, 4pcb.com (Advanced Circuits), and jlcpcb.com, which offers 10 pcs for around $2 plus DHL shipping. Other options include Indian small-quantity prototyping services, and companies like zaponpcb.us and wellpcb.com offering online quoting and ordering with promotions. Some recommend in-house PCB fabrication using laser printers and manual methods for cost savings and skill development. The discussion also highlights the importance of quality features like solder mask, silkscreen, FR-4 material, and plated through holes. For small prototype runs, services offering specials (e.g., 4pcb.com's $33 each for 4+1 boards) or batching services for DIYers are noted. The trade-off between cost, quality, and delivery time is a recurring theme, with some emphasizing professional fabrication for better quality and others advocating learning manual fabrication skills. Several providers offer online ordering with competitive pricing and quick delivery, including US-based and Chinese manufacturers.
