Thank you for the links neo. I must admit, with the rapid posting rate on the forum, I had not read in detail all of your posts. Thank you for pointing out the ones you thought most informative. If you have any other comments or information, I look forward to hearing it. To anyone else following this thread, please do not hessitate to post some information for me. I do not have time to read a dozen books, but in the future I may be able to read the suggested texts, and any summary information would also be greatly apreciated. Thank you all for your time once again, Mike
