Go for it! The best thing about pumps is that they are not permanent. So, if you don't like it, you can just go back to shots (I think they will even refund you within 30 days). You'll be out some money for supplies, but that's it.
It can be a bit of a process to get started on a pump, so make sure you have the time. There are multiple endo appointments, meeting with a dietician, and meeting with the pump trainer. Yes, they will make you do all this even though, after 16 years with D, you probably know more about it than the professionals. BUT, once that's done with, it is just a matter of figuring out basal rates and really learning how to work the device.
The Good - You can sleep in, you can adjust your basal rates on the fly and exercise and eat more freely. The pump also records EVERYTHING (provided you use the wireless meter it comes with), and for me this was a LIFESAVER because I am a horrible logger (I mean, who the heck has time to write down every little thing they do?? NOT ME!) You can achieve tigher control because you're only working with fast-acting insulin and can create multiple basal rate patterns. I really love the "patterns" option because there are certain times of the month when I need more insulin. During these times, I simply use a different pattern that I've preset. Ability to dose insulin in small doses is a HUGE benefit because it means you can correct small highs, thus achieving better control. If you have dawn phenomenon, you can get rid of it.
The Bad - Infusion sites that fail, you have something hanging off you 24/7, you have to think about it when you buy clothes (although not that much because the pumps are pretty small now), you can develop scar tissue, you have to really watch out for DKA, you have to test a lot, figuring out basal rates can be frustrating, there's a learning curve. The pump costs more - even with excellent insurance, I have quite a bit more out-of-pocket expenses for pump supplies.
Get the book Pumping Insulin and READ IT. Twice. This will give you a good overview of how the pump works. If you're interested, see your endo and begin the process. Depending on your situation or insurance, it can anywhere from a couple of weeks to several months to get approved. Even once you receive the pump, you have to jump through hoops to meet with a trainer and such. It's a bit of a hassle, but the benefits are great once it's all done.
As for pump brands - there are three in the US right now: Omnipod, Minimed Revel, and Animas Ping. The Ping and Revel are both with tubes, and the Omnipod is wireless. I use the Revel and love it. When I was looking to go back on the pump, my endo told me flat out that she will not work with the Omnipod. I know some folks who have the Omnipod absolutely love it, but they have quite a few more issues compared to the tubed pumps. If you're prone to DKA, I would advise staying away from the Omnipod.
Comparing the Revel and Ping, they both have similar features. The Ping has a brighter screen, but requires more button pushing to bolus. The Revel has an integrated CGM that you can get; I don't currently use the CGM with my Revel, but I do use one on occasion to see how things look and I love the integration. Having to carry around one less device is a HUGE help. Just from what I've read online, the Ping seems a tad more delicate than the Revel. Minimed has been making pumps for like 20 years, and the Revel is a really durable little machine.
The revel comes in two sizes - one holds 180 units of insulin and the other holds 300 units. The Ping only comes in one size that holds 200 units of insulin. So, think about your total daily dose (TDD) of insulin when choosing a pump.
