If you're comfortable with wiring things and comfortable being methodical with your keypresses, an upgrade to a vista20p, in my opinion is not that bad. You're right on the cost, not too hefty, and yes, most of the sensors should be compatible - but easily replaceable piecemeal if not. The hardest part is programming, but the programming manuals are pretty good and there are lots of tutorials out there.
