What is the lightest, smallest fold stroller you can...

...attach a buggy board to?

DS1 is still in need of resting his legs when we go out or if I'm in a hurry. I have an explorer for around town but need something for weekends away, flying holidays etc. I was considering the Zapp, not the Xtra, but I read that a buggy board doesn't necessarily work well with it.

Are there any other options?

I should say budget is around th Zapp price, I'm going to sell my smart to fund it (love the stroller but the fold is not small enough). We have no room in the apartment to store the 2 P&T strollers.

Have a look at a second hand BJCMini or Micro. Although the fold is larger than a Zapp it's very slim with the wheels popped off. Ours slides nicely into a gap. There's a lifetime warranty on the chassis. Other than that I suspect you are looking at a Micralite or umbrella fold buggy.
