Best cheap stroller to use with Unity Baby Capsule?

[belfie]

I bought a P&T sports and love it. And I was going to buy the SNS baby capsule, but the SNS unity capsule was on a great special so I bought that instead. And now, after 4 months of lugging around my boofer boy (7.6kg) in the capsule (while my phsyio tells me to stop doing heavy lifting) it's suddenly occurred to me that I shoulda have got the stroller that goes with the capsule!!! I already have the indefinite loan of a Steelcraft Phoenix stroller (from MIL) which I use for shopping centres - but that doesn't fit the capsule. So saying, so I don't really need another umbrella stroller. BUT I've realised if I get one of the compatible strollers that would be a much better way of doing things (and easier on my back too!). So I saw that the Steelcraft Enigma Layback or Profile Layback are both compatible with the capsule. I'm toying with trying to get one second hand or just shelling out for a new one.

Soooo... my questions are... is it worthwhile getting it when he's already 4 months old... i figure i'd probably get plenty of use (and he's only gonna get heavier!) - for mebbe another 8 months (hopefully he won't hit 12kg before then!) with the capsule and of course I can still use the stroller after that. Plus we want to have a second fairly soonish, so would I get the use of it again once I've got the second bub, or end up using the P&T more with the two? (ideally we'll have about a 2 year age gap between them. DH was a bit confused as to why I'd need it - but when we're together, he carries the capsule. It's those short trips & appointments where I'm either lugging the capsule (which is really not an option for much longer) or I have to get DS in & out all the time... just popping the capsule in the stroller and not disturbing him just seems like a so much better idea! (And TBH I have NO idea why the shop didn't try to sell me the stroller!). Anyways love to hear your thoughts.
