Just my opinion, you made a reasonable and rationalized decision. The wheels will undoubtedly be fine, much better than plain old utilitarian. Don't delude yourself, however, that you'll be satisfied enough not to "want" something more, especially new and flashy. If I was going to save for a future wheel purchase, it wouldn't be to buy a demo wheel set, it would be next year's big thing, and I'd be thinking SES 3.4 with nice light hubs, although even newer better more expensive wheels will surely hit the market before then.
