Registry: Big items thoughts ?

We pretty much went untraditional. Aren't going to do a registry at all because we both had our own homes years before we ever met, therefore, when we did move in together, we had 2 or 3 of everything.
When I found Zola and how you could customize it for honeymoon I made several 'add ons' people could buy for us to enjoy on our honeymoon.
Most were experiences, but some was random travel items and I did add a few nice wedding albums and scrapbooks as well.
Our "activities" or "extras" included things like upgraded unlimited drinks package $500, snorkeling $150, couples massage $280. But we made all the big ticket items where multiple people can contribute. We also added some real small items (I think our guests would add those on with something else) like room service $8, etc.

I already know my mom got me the kitchen aid limited edition blue color I wanted because it was on sale a couple months ago and she told me not to put one on the registry! My roomba then is the other high ticket price item. I was unsure about it because it is pricey but I really hope someone purchases it for us! Every week I have to yell at my fiance to not wear his dirty boots in the house. He's constantly tracking in stuff and I can't even walk around barefoot in peace! Lol The roomba would be a heavily used item in our household.

KitchenAid mixer. I've always wanted one. Fiance has some sort of kitchen gadgets I don't understand.
