Craftex is the Canadian import brand for generic 15" planer made in Taiwan.
It's a clone of the US made Delta/Rockwell RC-33, and likely identical to the 2HP Delta DC-380 made in Taiwan.
If you are used to a lunch box portable planer, there is a big difference. The 4 post planers require more maintenance, plus take more time to set cutter knives, and tune the machine for best performance. It is big step up in thickness planing machinery.
The 15"Taiwan made planers are reliable machines, but have many wear points that need attention. In particular they have have bushings on the in/out feed rollers that require weekly oil application during use. Most machines used in an industrial environment I see those bushings nearly destroyed, allowing shaft play, and needing replacement. Another challenge is the condition of in-feed and old-feed rollers. They are solid steel, and prone to rusting during storage. The rust transfers to wood until gone. It's easy to clean up, just takes time to tear it down, remove rust, and reassemble.
As far as pricing:
Used in great working condition, a fair price is about 50-60% of new Grizzly machine price ($500-600 USD). If they need a rebuild, or any new parts, subtract it directly off the price.
Have rebuilt a couple of 4 post planers. You can replace all the bearings (~ 23 in motor, cutter head, gear box, and conveyor) for about $150-180 USD in parts. Adding gaskets, seals and new bushings; will send ~$220. The only cost challenge is when you need to replace feed roller, which runs $100-$150 USD each. As long as cast iron is not damaged, even a fugly 4 post planer can be salvaged if bought cheap enough.
One nice thing about those planers is that Grizzly, Jet, and Powermatic are still buying newer versions of same 4 post planers from same mfg made 20+ years ago. The original top mounted motor has different parts now, but there are many common parts between these machines. I have not had trouble finding a replacement part, even if I had to put a Grizzly bushings ($8 each), on Powermatic PM15 machine as PM wanted $32 for same part.
PS - Note that there are two different mfg of clone 4 posts planers with subtle differences, so not ALL 15" planers are identical, even they look exactly same. But both mfg are still in business/imported, and wear parts are relatively easy to find assuming you look to alternate brand name sources.
Best Luck.
