$50 amazon gift card, what to buy (BBQ)

So, I've been smoking every weekend basically. Starting to get the hang of it. Finally broke through a barrier the last two times and it's become much easier even with my cheap little pit. Wife got me a gift card for Father's day. Problem is, I already bought the only thing I really had my eye on (wireless dual probe thermometer). I honestly haven't found the need for much else, but I also am new, so there may be some toys I don't know about. Looking to upgrade the cheap pit to something nice this winter, so would like something that would carry over. Any ideas? Could be a little more than the $50.

I just can't have "free" money sitting there doing nothing, so I need to buy something. I've got two hobbies right now and I've damned near bought everything possible for the other
