Timing vs value

We’re closing in on 6months age and while I’ve no plan to stop breast feeding any time soon I do know that’s not always choice. Whether it be the baby choosing solids and loosing interest or the mom body just saying it’s had enough, things happen.
I would really love a new pump, drooling over the air 1s since launch but I just don’t know about spending so much at this point. The thought of buying to only use another couple months makes my head ache.
Personal experiences on such?
