Welcome (back) in the forum, Ian!
Time has passed, PSoCs have evolved...
I hope, I am not suggesting against Cypress's policy, but I would suggest you to have a look at PSoC4 chips which are quite more modern, have integrated debug capabilities and come for a reasonable price. The development software Creator 3.3 can be downloaded for free (as Designer 5.4) and the prototyping kits come for just $10 (including the Kitprog for debugging).
I have had a look at the PSOC4 and PSOC Creator over the weekend, something quite different from Designer, but once I got your head around it, it became quite trivial in design.
