So...it seems Disney DID in fact release the first two seasons on DVD, but it's news to me! They're on Amazon.com, but ouch! $50 and up!

I've vouched for the series before, and I'll do so again. It is an excellent series that deserves to be watched. I suspect you would enjoy it as well, although at this point I think you're better off seeing what you can for free online, as the box sets are expensive!
