What a fun question! I love kitchen gadgets! I have a weakness for them! I love to go to places like Tuesday Morning or TJ Maxx and browse their sections because you can frequently find them at discounted prices. Especially with this economy, I have made a new rule for myself that I will only purchase discounted items. Fortunately you can find many gadgets through store sales, yardsales, etc.
I have several gadgets that I use weekly, but my top ones are:
My Vidalia onion chopper. buffetfan, it sounds like your alligator is similar to one of these. I LOVE it!! I had one of the imitation ones at first and hated it. Someone told me to get the "real" one and I found one at a good price on ebay (she had received two as gifts and put one up for auction-it was brand new!).I decided to go for it and I now use it regularly! I probably could keep it out on my counter, it is used so much. During the summer months, I buy bulk peppers and vidalia onions and chop and freeze them for use throughout the winter for my recipes - right now I have over a gallon of frozen viadia's in my freezer! LOL! I also use it for making salads (chopping the veggies), soups, etc. LOVE IT!
I also use my old Weight Watcher's electronic scale several times weekly. I LOVE that thing, too! It is perfect for all kind of food measuring - and even helps with an occasional science fair project or two, too! LOL! Once again, it was a purchase made based on a friend recommendation and now I couldn't do without it. I buy food in bulk and freeze them in serving sizes - this helps me weigh out the portions. I use it for general cooking, too. Another one of those "I will cry when it dies" gadget.
I have some other favorites - a favorite spoon that is heat reisistant to 500 degrees (a Tuesday Morning purchase for 75% off!); a favorite mixing bowl; etc. And whereas this doesn't fall into the gadget category, I also just recently switched over to Corelle - again, buying dishes on clearance price at a Corelle store - and LOVE those things! I wish I had purchased some years ago! I used stoneware prior to this and never realized just how heavy those dishes were! I am loving my Corelle, too!
