I got a second hand Bee+ recently. Its a great little pram and the buggy board rocks, its perfect for DD (almost 3). My little one is going to be tall so I liked that the Bee+ has extendable length. The new buggy boards can fit a seat on them which you have to buy from Europe. I haven't bothered.
There are a few things I'm trying to get the hang of, one of them is the harness, it doesn't seem to fit very well and is awkward to adjust. Its also difficult to remove the seat if you need to and to open the stroller when its rear facing. But fits well in the car and looks awesome!
thats what i liked the adjustable seat!!!
DD who is 2.5 sat in one at the shops and it looked so cosy for her!
