four wheel rollator/walker (upper east side)

Hi I am a senior that uses a rollator/ walker, the type that uses handbrakes for getting around outside as long as in working condition my current one the wheels are very worn thus my reason for replacement perhaps you have recovered from a injury and no longer need it I can definitely use it. I can pick up ues or uws manhattan,or anywhere a mta bus goes as I can not do subway stairs Thank You and have a wonderful holiday!
