Hi all, Thank you all for a flood of very useful information and advise. I was not expecting this much and am very grateful for everyones input. I'm going to follow up with some of the questions and comments individually to spare the list of a barrage of replies, but wanted to thank everyone for their time! Thanks! - Ben -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
