There is the BARCUS BERRY 4000-XL which sells for around $300 US. I don't much care for them unless it is used in combo with a good mic set up, but they work pretty well. You can buy the crystal for around the $100 mark as well.
These guys make what I consider one of the best piano pickups around. www.helpinstill.com/users.html
While they do have a model over the $1000 mark they also have some around the $500 range as well.
I've used Piezo's on piano before. But to do it right you are not going to get the job done with a single piezo.
