Advertisements Greetings! This is my first posting here. I have a XL4 and an S3 both with lifetime and in perfect working order. I am going to post on various sites (probably not ebay). These are legit units, I am the original owner and I can provide proof of ownership and lifetime status. If you have any interest in these units (and are in the seattle all the better). I hope to find a new owner for them soon as I am cleaning out my office! Please let me know! Thank you!
