I just looked at https://www.parallax.com/ and it seems the BASIC Stamps are being EoL'd, but their remaining stock is on sale. The Propeller (the follow-on to the BASIC Stamp) is kind of interesting and the site implies you can run PBASIC code on the Propeller 2 ( you learn something new every day. ) I used a BASIC Stamp way back when and it wasn't a horrible experience. People dis on BASIC, but if you have a simple app, it's not that bad.
