Inexpensive algebraic programmable calculator
I recently purchased a Sentry CA756 Graphing Calculator new in it's package at a thrift store for $7. This model is commonly available at Amazon or Big Lots discount stores for under$20. As a graphing calculator it has a lot to be desired but as an algebraic programmable calculator, it is surprisingly capable. The following brief review from Mike Sebastion at rskey.org details most of the major features of this model.

It also features full alphanumeric text input prompts and output labels (12 characters max).  As far as program speed of execution, it's not too bad.  A simple addition loop program counts to 1,915 in 60 seconds. This is around the program execution speed of a HP-42S according to the following benchmark site.
