At $6.50 wholesale and my guess would be about $15 retail Weigle Framesaver, and that treats 3-5 frames, is the only choice for me.
Now if I was a real penny pincher, and I have been know to pinch them and other things on occasions, I might consider LPS-3 on a Varsity or frame that has wall thicknesses of gas pipes.
