All of those early accelerators are hard to find now. I recently got a Radius 25 but I had to buy a whole SE that was broken to get it. I don't think the seller quite knew what he had or I'm sure he would have set a reserve on it. I only knew what it had in it because of a discreet Radius sticker on the front panel which the seller misinterpreted as a model name. I think I ended up getting the whole thing for like $45 shipped, which was pretty cheap considering what an SE weighs. Now if I could only find a 25mhz 68882 that doesn't cost $100. >
