Choosing an industrial woodworking CNC router usually comes down to how much working area, spindle power, and setup support you need. These four versions share a 4040-PRO model name, a 400×400×83mm effective stroke, and a 75W spindle, but they are priced differently enough to matter. The least expensive version sits at one end of the range, and the top-priced version carries an extra "+ RC" label. What changes between them is the included setup bundle and the RC designation, not the machine envelope.
Quick Take
The cheapest version and the version only $4 above it look nearly identical in the described specs. The middle-priced version is the one that spells out a setup bundle with a Z probe, clamps, a power supply, and manual. The highest-priced version is the only "+ RC" option. All four are marked new and share the same 4040-PRO working area and spindle.

Decision Matrix
- Choose the lowest-priced version if you want the minimum upfront cost.

- Choose the bundle version if you need the setup accessories spelled out.
- Choose the + RC version if the RC label is what you're after.
Product Notes
4040-PRO at USD 327.39
This is the lowest-priced version in the group. It carries the same core 4040-PRO spec set as the others, so the full machine envelope is there without the higher price. If you already own clamps, a probe, and other setup tools, the lowest price keeps your upfront spend down while still giving you the same working area and spindle. The trade-off is that the description doesn't name the setup bundle that the middle-priced version spells out, so you are paying for the machine itself rather than a package of extras.
4040-PRO at USD 331.39
This version is $4 above the cheapest option and shares the same described core specs. It holds the same 42 two-phase stepper motor and 6,000rpm rotation speed as the cheapest version, so the two are functional siblings. There is no described specification difference between the two, so the small price gap comes down to which of the two options you prefer. The limitation is that nothing in the description gives this version a separate feature advantage; it is effectively the same machine as the lowest-priced option with $4 added. If the lowest-priced version is what you want, this alternate keeps you in the same territory.
4040-PRO at USD 363.39
This is the middle-priced version and the only one that spells out a full setup bundle: cutter, Z probe, right-y-axis, U disk, USB cable, power supply, power cable, clamps, manual, and other installation accessories. The core specs are still the same 4040-PRO envelope, so the extra cost goes toward the included accessories rather than a larger machine. The trade-off is that you pay $36 more than the lowest-priced version for the same working area and spindle power. If you need the bundled pieces, this is the option that names them; if you only need the router itself, the cheaper versions focus on the machine specs without those extras.
4040-PRO + RC at USD 438.34
This is the only version with "+ RC" in the product title and the highest-priced option in the group. The extra label is the distinctive feature, and the rest of the 4040-PRO spec set stays the same. If you are looking for the RC-labeled variant, this is the version that matches that request. The practical limitation is that the price gap is large: $110.95 more than the lowest-priced version, while the listed specs are the same as the other 4040-PRO models. That makes the plus-RC designation the only clear reason to choose it, and only if that label is specifically what you need.
Final Recommendation by Use Case
If you want the most clearly explained setup bundle, the middle-priced version is the one to look at. If you're buying purely on price and already have the supporting pieces, the lowest-priced version is the leanest way into the same working area and spindle. The $4-higher version is a near duplicate of that low-priced option, and the + RC version is the one to choose when the RC label matters more than the price gap.
