Clammy - it sounds like you've gotten the advice you've been looking for, and it also sounds like you're pretty much set on what you want. That's all fine, if and when you decide to take Fundies, you can re-evaluate your purchasing decisions and get anything you're missing to be compliant for a pass in the class.
But if as you say cost is really the limiting factor, I strongly encourage you to heed the advice of others above and go for some used equipment. I got a near-mint Halcyon wing for $150 and Agir-Brokk for $200, well under half of what either would cost new. You'll likely save more money than you would with your OMS discount, won't have to cut things off your wing later, and won't need to worry about whether an instructor will have a hissy fit over how the extra grommets will grow arms and choke you to death in a cave. Everybody wins.
