I picked up a second-hand 11x14" V-Track over on the LF forum recently, and I'm really pleased with it. Before I had an old Honeywell-Nikor 4-blade easel kind of like the traditional style Saunders easel with the knobs, and it was never in good alignment. I was always having to tape down the paper positioning blade to keep it square. The V-Track is perfectly aligned and smooth to adjust. The footprint is larger than other easels, but there is nothing outside the footprint to catch on objects or cords next to the enlarger, and it's heavy with a nice grippy pad, so it doesn't slide at all on the baseboard.
I'm sure Murray's got his easel by now, but if anyone else is looking for a four-blade easel, I highly recommend the V-Track.
