Sometimes timing is EVERYTHING! Recently I tried to buy one of the new aluminum blocks from Barry R., and was waiting on a phone call back to give pertinent information for shipping, etc. During the couple of days it took him to call me back, I had several things happen, and it was unfortunate that I was unable to answer the phone when he did call back. Since then, I have had many, many things happen that have taken much more than the asking $4200. for that aluminum block. Just today my insurance adjuster finished with checking my house, garage, and tool shed for hail damage, and they will require a complete replacement. I know Barry, DSC, and others are busy, so give them the benefit of doubt that they are intentionally not calling back at your time schedule. For me, I still want one of those blocks, but my wallet needs a few weeks to regroup. Just saying, timing is everything in the machine shop businesses. Joe-JDC
