ISTKT & DYNSQL vs. 5722ST1 SQL Development Kit

All,

 Our iSeries shop is small, with an even smaller software budget so
purchasing the IBM SQL precompiler (5722ST1) simply isn't going to happen.
We've muddled by with OPNQRYF and ASC's "Sequel" product (which is a great
tool) but without the ability to embed 'Select' statements into RPG or CL,
we've not been able to take full advantage of SQL.

 Until yesterday, that is, when I girded my loins, plunged into that scary
SourceForge site, imported the "iSeries toolkit" and stayed up past midnight
playing with DYNSQL.

 It appears that DYNSQL will enable me to build dynamic SQL statements,
declare cursors and fetch results directly into RPG and CL. What more could
a guy want? DYNSQL requires a slightly different syntax than IBM's
precompiler, but those are just technical details, right?

 So I'd like to:
1) say thanks to David Morris and his compadres for making this available,
and

2) ask whether anyone else has used DYNSQL instead of IBM's offering and
what differences I should be aware of (other than syntax) between the two
products. The goal is not to chuck all the native I/O, but to enhance it
where the payback is greatest. Count(*) and Sum(amount) now become easy, as
well as dynamic sorting and filtering of subfiles. 

Many thanks, JK
