when I got my first P&T I got it from here

I would look around as there are always specials that come up.
Not sure where you are but Kiwibaby in Auckland often have good sales, I got my second one from them.

I sold my P&T E3V2 double for a good price on TM & when I sold my Sports one with double kit, covers, bags, lazy ted, & a few other accessories I got $900+ for it, it was in great condition & was used as a car basically 5 days a week in good & bad weather. Few things I sold separate like the cocoon I got all my money back on as I bought it on sale.
I think if you can spend the money on a good pram & it is a model that resells well in NZ like P&T or MB then you will get a big part of your money back if looked after.
Also you don't need to buy everything at once. You could get the single pram to use now & get the other bits later.
