JB,

If you only have room for one tree, get a familty pear tree - I bought
one for my garden it has Beth Concorde & Comice. Compatible polination
groups and a stagered cropping - best of everything!

What I'm not sure about is what root stocks a family tree would be
available on - and you will want a dwarfing variety.
