VTech Baby Monitor - Parent Unit (Melissa)

Hello! The parent unit for our VTech baby monitor finally died last night =/ The model (VM344) is no longer being manufactured. Our "baby" just turned 3 years old, but we still find the video monitor to be useful at nap time at at wake up time in the morning. Not useful enough to pay the price for a used unit online, however. Does anyone happen to have the parent unit for VTech Model #VM344 lying around that we could have? Thank you!
