Alright. I've decided. N900 it is. This thread definitely helped me decide.

Since I will inevitably (read: hopefully) get my hands on a Neo900 one way or another, I think getting an N900 is the best way to go. From what I've seen, it's relatively cheap to boot. Plus, I can save money while also supporting "the little guy" by getting the NeoN board as an upgrade.

Now, I don't have a Paypal, nor do I have any intentions on making one. Can't I just pay via credit card on eBay, or does that vary from seller to seller? I'm not familiar with eBay.

The Amazon listings aren't bad (although some are outright ridiculous), so I should be good there. I think the safest way for me to go about this is to skirt by local Radioshacks and second-hand shops to see if there's a random N900 anywhere. That'll be a start.
