The used ones I have found on line at various sites look pretty sketchy. I just did not want to spend the time to order it, get it, send it out for repair and then finally get it back working to be able to use it. My wife agreed that I should just go for it, I think she is tired of watching me take an hour or 2 to get the system up and running. I am going to order it today and have it sent to or 3rd stop for here on or around 4/23. We leave here tomorrow then a 5 day stop where we can not get shipments and then a 1 night stop. We will be at NAS Lemoore for 4 nights and they will except shipments and mail prior to us arriving.
