I have been using the Medtronic Paradigm 523 pump for about 2 months now and I LOVE it. Probably the best thing that has ever happened to me since I was diagnosed w/ Type 1. It was pricy (something like $6000), but if you have good insurance or the money to spend, GO FOR IT! (My insurance covered the entire cost of the pump plus supplies. :-D )
The only issue I have had were with the infusion sets. I kept having problems with the plastic cannulas on the Quick Sets, but since I switched to the infusion sets with metal ends (Sure-T), I haven't had a single issue. My blood sugars before going on the pump averaged in the 170's and 1.5 months later, they were averaging in the 140's and continue to improve. I have not had any issues with the pump itself.
As far as ease of use...it doesn't get any simpler. It is A LOT easier than giving manual injections, in my opinion..not to mention much more precise. You'll see a Medtronic representative who will instruct you how to use it and, with your doctor, will help you set the bolus/basal settings. For meals....test blood sugar, enter in # of carbs, the pump will automatically calculate your dose based on your personal settings (to the tenth of a unit), press a button and it will start giving you insulin. For random highs, it will calculate your correction dose, subtract any insulin on board, confirm the dose and it will start pumping in the dose. The basal insulin will constantly pump into your body all day & all night without any intervention. Another nice thing is it will always tell you how much bolus insulin you still have on board...which is great, especially for bedtime testing.
If you don't currently see a diabetes educator, i'd strongly recommend making an appointment with one. It only makes it that much simpler and ensures proper settings and continued adjustments.
It does require a lot of testing, especially in the first couple of weeks. I was testing 8-12 times a day my first 2 weeks, but it is worth it.
One more nice thing about the pump is the temporary basal feature. Whereas with Lantus (or other long-acting insulins) you are sort of locked in when you can eat..with the pump you can eat pretty much whenever you want. And I find that I have considerably less # of low readings while I work out because of the temporary basal feature. Oh, and it is nice to only have to 'inject' myself once every 3 days rather than 4+ times everyday.
