Well I just ordered my R4. Its backordered 1 week, then it says 14 days for shipping.. Lame!
It was 32.51, but when I paid with Paypal, I had 15 dollars credit from the coupon I posted earlier this year. So it was cheaper than I thought.
I'm going to get a 2 gig microSD card in the next few days for 19.99. Then, I suppose I'll be waiting for the DS Lite. I'll probably wait a month or two, until I get another Best Buy 10/12% off to use.
