I used a Beseler MXT 45 for several years. I personally didn't like the motorized chassis, but I can see where many would. I prefer the accuracy of the hand crank for where I want to stop. There's a knob for fine movements when you get the head close to the position you need. I did have problems with alignment but it may have been just due to the fact that it was well used and worn when I got it. A nice feature on the Beseler is that you can tilt the head up and make monster size enlargements on a wall if the need ever strikes.

I'm now using an Omega D5 XL which I love. I didn't swith for any particular reason than I got a great deal on the Omega. The Beselar served me well when I had, but as mentioned earlier, it was my starter enlarger and was in poor shape.
