Trion PS(B)300 Guide Stop for Sale or Trade

[jkanter]

I have a brand new Trion Guide Stop...works with both the PS and PSB.  It was taken out of box(box not available) but never even used so absolutely perfect condition.

I'd prefer to trade it for an HSK 80x133 Hand Sanding Block.  That's the item I could use the most right now. If interested as sale, it would be $20 shipped in continental US.  Thanks!
