To update... I found a used Casio WK-3000 on Craigslist for $150 and bought it today.
The link can be found here:
SUPER MEGA AWESOME KEYBOARD Casio WK-3000 Professional Series 76
It received positive reviews on Amazon (
) and seems to be a nice fit for me.
The quality is great, and it came with a stand. I browsed a pawn shop as well as two music stores and a piano-specific store today, and this deal was easily the best I came across. I'm very satisfied with the purchase.
Now I can focus on learning and the methods by which I intend learn with. If anyone has recommendations in regards to books, websites, or methods of piano teaching, please share them.
I played violin through high school and can/could read music, but it will take quite a bit of refreshing and playing to get back to where I was; especially when considering I'm dealing with a different instrument as well.
I really like that headphones can be plugged into the keyboard and used, as this will make practicing in the evening bearable for those in earshot.
