So last month I took a flier on a Chinese knock-off rail square (Fonson) from Banggood. Cost $60 plus shipping, and as usual, shipping time was like 3 weeks.
Just came in, and honestly I'm quite impressed. Nicely machines piece of aluminum, fits securely to my Powertec track, and is square when compared to my PEC combo square.
There was also a recent Hooked on Wood episode that reviewed them positively (though wasn't available at the time I purchased). I bought the larger version, but there is a smaller square for $30 that apparently works well too.
