Hey,
thought i'd give my 2 cents
Firstly glad you've got what seems like a great team now, very positive with encouraging carb counting and no fuss with getting you on track with a pump!
All pumps are similar but depending on what you want from your pump, some will sway you more than others.
When i researched pumps i particularly like the accu chek combo, because of the remote and it seemed so have all i was looking for.
My hospital only do one pump, this is quite common as they strike a deal to get them cheaper so result being they can buy more pumps for their budget.
My hospital luckily do the accu-chek combo so i got what i wanted out of pure luck.
Definately research all the pumps and what each one can offer you, you can also ask on here as there is a wide range of pumpers with most pumps you can get, if not all!
My hospital told me they chose accu-chek as they liked the service most, someone always at the end of the line if you need help, on most occasions i have found them to be brilliant!
It really does vary with time, some people can get it all done in a few months, mine took over a year but only because the pump nurse was off long term sick, but worth waiting for!
My lowest hba1c pre-pump was 8.4% and now it's slowly come down to 6.6% all thanks to the pump and reward of hard work that a pump takes.
These are a few things i had in mine whilst 'shopping around' :
whats the lowest dose it can give - mine gives 0.10U some can go as low as 0.025. So if you are insulin sensitive this can be important.
What infusion sets are available with the pump - Steel, teflon, sizes etc
Does it have a bolus wizard - meaning a bolus calculator so you enter the carbs and it will work out the dose for you. Easy and quick!
Is it waterproof - mine is water proof up to a certain depth but i wouldnt try intentionally dunking it, it's nice to know if i get it wet it wont kill it!!
How big is the pump - i wanted mine to be easily concealed, i consider my pump to be nice and small
colour - some pumps you can get them in purple, blue, mine comes in black but you can get coloured skins and clips etc.
Durability - if i drop it will it break - i've dropped mine only once, its a tough cookie i reckon!
data/graphs - howmuch info will it hold, will it show me graphs of my results and does it have software - it's all a yes with my pump.
It it easy to use - i think you CAN stuff too much into a 'gadget' complicate it that much with brilliant things that some people may find it hard to use. Mine is pretty straight foward and user friendly i think.
If you go on websites, they may do the same as the accuchek one, you can 'demo' the pump online and see the dimensions etc. maybe other manufacturers will do this too, very good idea!
Keep us updated on how you get on, and ask any questions you like, we were all in your boat at one time or other so we know how intruiging and complicated it can get at times when first looking into things
