Blue Earth Research sells a similar BASIC compiler (written by the same author) for $295. It is 100% compatible with their slightly modified version of 8052-BASIC. If you can describe your program to me, I can tell you what speed gains to expect.

If you prefer, I could compile your source file (one time only) and send you a hex file to try for yourself...

Let me know if I can help.
