30" v 36" Slate

I've zeroed in on the Slate but can't decide between the 30" and 36". We are a family of 4 who entertain occasionally but not often. The 30" is readily available locally at Ace whereas I'd have to order the 36". Dunno how long it would take the ship. But of course the biggest factor is price. I know that no ever regrets the bigger grill/tv/etc, but that extra $200 would buy a lot of accessories. So, if you have a 30" Slate, do you ever regret not getting the 36?

And FWIW, the guy at Ace said there would likely some Labor Day sales, so I'll likely wait until then to buy.
