I'm a Roche Combi pump user
They are good pumps indeed, and the remote handset is very handy....
Roche is upgrading the Combi pump, and the new version will take prefilled cartridges the new pump will be released any time soon and I think those getting new pumps prior to it's release with get an automatic upgrade to the pump as soon as it's released.
When I was looking around in the summer as my old pump was at the end of it's warranty, I decided that I would stay with the Combi pump.
I find that the ability to change the basal every hour is very handy, other pumps have one one hand a slight more flexibility with be able to choose the exact time so if you want to change it 20 minutes past the hour you can, but the segments changes you can make were a lot less. Which considering that I have 13 changes in 24 hours on my main profile meant that it might not be that suitable for me
The other aspect I liked at is the screen...
I've just started needing reading glasses for small print, so do find that the screen not the easiest of screens to read If I haven't got my glasses to hand, but I have no problems reading the handset screen.
I looked at the omipod, but I actually don't like them, if you lose or forget the handset you have only very basic controls on the pump itself, can't change the profile and only a standard bolus!
Another thing I didn't like about it, is leaves a lump under the clothing don't like this idea at all, the infusion sets don't show under clothing, and the tubing is easily hidden out the way.
You say you aren't keen about the pump not being waterproof, I assume this concerns swimming purposes, you can disconnect the pump for swimming, and there is several ways you can handle the detachment of the pump, Some bolus the background basal that they are going to miss during the session, others decided to await until afterwards. It's a case of trail and error to which works best for you.
Two other problems surround the omipod with swimming, firstly the pump itself may be waterproof, but how could is the adhesive holding it on, secondly the size of the pump means the lump it creates under a swimming suit will be quite notice able, if wearing a bikini then it's going to be very noticeable. An an infusion set is pretty discrete and if seen, others just see it as a plaster.
As to control
Pumps are a lot more flexible than injections, very good for keeping up with the fast changing needs of a growing child. But it does take some hard work to get basal setting correct, work out all the carb-insulin ratio's etc... They aren't a plug and play that a lot of the promotion blurb suggest they are.
