I'm new to posting the forum though I've been reading the posts for a while. I'm currently running a Universal PLS 6.75 60 watt laser that we use primarily for stone etching and brick engraving. Because of the materials we spend the majority of our time laser etching, we get a ton of requests to sandblast on natural stone. Most of the stones we would be doing could fit into a standard cabinet, but we do get the occasional request to do boulders, which just wouldn't fit.
After all of my research I guess my big question is: Is it worth it to spend the money on the all inclusive Rayzist system or is the smart move to build our own system from Harbor Freight? I suppose my biggest fears with going the HF route would be how effective the filtration and media reclamation would be, but the biggest positive I can think of using HF is that the pressure pot would be independent of the cabinet and could be used on boulders and other objects that wouldn't fit into the cabinet. I'm open to any and all opinions on this.
