I bought this Bald Eagle about 1 month ago to clean parts for restoring old tools. I needed the length this machine offers to be able to get a majority of the parts cleaned ultrasonically. You can't beat the sale price of $370 on this bugger. Heats well, cleans well. I've put it through the paces by running it nearly constantly for 8 hours a day, 5 days a week for the first couple of weeks and them about an average of 3 hours a day since then (the instructions say that it isn't supposed to be run constantly the way I have but so far, so good). There has been one compromise, though. About 3 days after using it I noticed one of the cooling fans started to squeal (sleeve bearings). I considered calling up Grizzly to see if I could get a replacement but I'm the type of person that rather make improvements so I don't ever have to worry about shoddy parts again.
SO, I replaced the three (I believe there is a 4th hidden behind another panel but I didn't go that far) cooling fans with a dual ball bearing version that should outlast the machine. They were $5 each on ebay. Replacement fans are 40x40x20, 12V, .12amps. Should you decide to do this, pay attention to where the fans meet the panel that holds them in as this is fairly important. I had to drill the mounting holes to a larger diameter on the back side of the fans to mount properly over the posts they fit onto to the correct depth to be the correct distance to the back panel. Nothing a drill press with a depth stop can't handle. Also, clip the connectors off the existing fans and solder onto the new ones so they can plug-n-play easily. Best 'o luck!
