If I were to buy an LED model...

Hi Dave,

You will have a hard time finding either a Woodstock such as the HP 27 or a Spice such as the HP 33c in good working condition. If you do, you will have to pay a king’s ransom for it, especially a Woodstock. The Classics such as the HP 55 were bulletproof, and there still are many to be found in good working order for a reasonable price. If you are willing to dispense with programming, you can easily find a clean HP 45 in good working order for under $100. Also, you can power the non-cardreader Classics directly from the AC adapter without a battery installed, whereas you cannot do this with a Woodstock or Spice.
