The upside was that you had a company that actually cared about customer service. If it was broke, they fixed it, quickly. A few months ago, our phone line went out. Verizon said they would fix it in about 6 days. (We have no cell phone service here at the house, so we had no phone service at all, fortunately the cable was working so we had internet access) I think they actually got it fixed in 5 days. -- --- Chris Smolinski Black Cat Systems http://www.blackcatsystems.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
