Yes, I'm very glad I found it. With the exception of graphics, it seems to deliver on all of the "maker promise" that originally excited me about the raspi, for a lot less, and with no issues actually getting hold of them.

I usually get them 10 at a time. Looks like the price went up to $26 :(
You can always try your luck on ebay. Looks like lots of vendors are shipping new ones from HK.
The '02 is just the '03 without a USB port and less flash. It can't fit OpenWRT.
Edit: Ahh. Looks like they superseded it with the TL-MR3020. The bad news is, it costs $33. The good news is that it has a software readable 3 position switch on the side that does seem supported under OpenWRT.
