Jump in, the water's just fine. Lamb is less common here in the states. It is usually quite expensive. I have found that it goes on sale after Jewish holidays and use that opportunity to stock up.
It looks like you have a rotisserie on that gasser. I have a home-made charcoal rotisserie that I use to cook leg of lamb. I de-bone it, then season with garlic, rosemary, and lemon. Then I roll it tightly and tie it up. I cook it on the rotisserie to ~140. I like to serve it sliced with creamed leeks.
