My mom's a music teacher & just has a small, generic RadioShack, 61-key (I think) electric keyboard. She commonly complains about there not being enough keys to play pieces that utilize the whole range of the piano. So, my brother and I are putting our money together to buy her a full-sized keyboard. Any recommendations? If you recommend a store, non-internet please.

Thanks.

If you have a MIDI connection to your computer, you may want to consider getting her a Fatar TMK-88. But that's not really a standalone keyboard. Otherwise, I've found that the cheapest 88-key keyboards online tend to run around $500 on up (which means that in the retail stores, they'll cost more).
