Hi corpgator,
First of all … congratulations on your new mattress. As you know I think highly of Brooklyn Bedding and the quality and value of the mattresses they make and sell 
Post #89 here talks about the different types of mattress protectors that are available and the tradeoffs that are involved with each type. There are some links there as well to specific brands but a google search would also be well worthwhile because prices and sources can change constantly.
I think in your case one of the thin and stretchy “membrane type” protectors may be closest to what you are looking for. If the one you choose has some stretch it will not change the feel of your mattress significantly and the slight possibility of increased sleeping temperature (which can be reduced with your sheets and bedding anyway) would probably be worth it. They also tend to be a lower price than the stretch knit cotton or wool protectors and may be a better fit for your budget. These would probably be the most common choice in your circumstances.
I agree … but unfortunately it’s a necessary evil to prevent the forum from being taken over by spammers. It’s only on the first post though and from the second post onwards it doesn’t appear any more.
