When you're shopping for a laser cutter, the first question isn't which brand to buy - it's how much machine you actually need. Two very different answers sit at opposite ends of the price spectrum: the OMTech AF3551-130, a 130W CO2 system with a 35 x 50-inch engraving area, and the Longer Ray5 20W, a compact desktop diode laser priced at a fraction of the OMTech.
Quick Verdict
If you need to cut large sheets, produce office signage, or work with materials that demand serious laser power, the OMTech AF3551-130 is the clear choice. If you're starting out, personalizing gifts, or working in a small space, the Longer Ray5 20W offers a low-cost entry into laser engraving and cutting.
| Machine | Price | Engraving Area | Best For |
|---|---|---|---|
| OMTech AF3551-130 130W CO2 | $3,999.99 | 35 x 50 in. | Large-format cutting, office signage |
| Longer Ray5 20W | $247.99 | Compact desktop | Gift personalization, small projects |
The price spread between these two machines is $3,752. That context matters because your choice will likely come down to budget and project scale.
Where the OMTech Wins
- The 130W CO2 laser tube provides far more cutting and engraving capability than a desktop diode laser.
- A 35 x 50-inch work area lets you handle full sheets of material, making it suitable for office signage and professional fabrication.
- Includes RDWorks v8.0 and CorelLaser software, plus water cooling, USB/Ethernet/USB flash drive data transmission, and CE, FDA, and CDRH certifications.
Where the Longer Wins
The price is the biggest win - $247.99 is an approachable entry point. It also has a built-in 3.5-inch touch screen and 4 connection modes, making it easy to monitor and control from the unit itself. For anyone doing gift personalization or learning laser engraving, the budget barrier is much lower.
OMTech AF3551-130 130W CO2 Laser Engraver Cutter Cutting Engraving Machine 2026

The OMTech is built for heavy-duty work. With 130W of power and an engraving area of 35 x 50 inches, it can handle large-format projects that would be impossible on a desktop diode laser. The bundled RDWorks v8.0 and CorelLaser software give you capable tools right out of the box, and water cooling helps manage the heat during long runs. It also carries CE, FDA, and CDRH certifications, which matters if you're buying for a professional environment. The catch is the price: at $3,999.99, it's a serious investment. It's also worth noting that the listed compatible operating systems are Windows only (2000 through 10), so if you're a Mac user, you'll need to plan around that. This is a machine for someone who needs real cutting power and a large work area, not a casual hobbyist.
Longer Ray5 20Watt Laser Engraver/Cutting Machine 24000mm/min

The Longer Ray5 20W is a completely different entry point. At $247.99, it's priced for a hobbyist or small shop that wants to try laser engraving without a huge commitment. The 20W laser and 24000mm/min processing speed allow for detailed work on wood, leather, and other materials. The built-in 3.5-inch color touch screen makes operation straightforward, and the 4 connection modes provide flexibility for how you send files. The most obvious limitation is that it's listed as used, so it may show some wear. Plus, with 20W of power, you're not going to cut thick or dense materials - this is mainly for engraving, light cutting, and gaining experience. If your focus is gift personalization and small projects, the price makes it an attractive starting point, but you should be prepared for its size and power constraints.
Final Choice by Use Case
- Pick the OMTech AF3551-130 if you have a dedicated workshop, need a large work area, and plan to profit from heavy engraving and cutting jobs like office signage. The $3,999.99 price is a business investment.
- Pick the Longer Ray5 20W if you're exploring laser engraving as a hobby, personalizing gifts, or working on small projects and want to keep the initial cost as low as possible. The $247.99 price gives you a functional machine to learn on.
