I have a split leaf Philodendren that only had 1 leaf when I bought it on clearance for $5. In the last 10 years it grew into quite a monster. A few months ago, I cut it up and turned it into 2 plants. (My friend has always wanted a start, but I'm going to surprise her with a full plant, already rooted ready to grow).
For me half the fun is bringing them back to life after the garden center has nearly killed them.
