Where can I get an r4 or m3 simply card?

I want to buy either an r4 (<- preferably) or an m3 card.
What places have them in stock. I can't seem to find one. Not any at least that are under $50. (looking in the $35-40 range)

Thanks for any help

 

Have you checked out dealextreme.com?
I got my R4 from there, they also have the M3DSS.

 

for anyone in the uk i can well recommend - http://www.addictsupplies.com/index.php

They always have R4 in stock, fast delivey and good service .
Hope you can find some good stuff

 

I bought R4 at www.itechextreme.com, the price is really good, just 59.99, if add 2Gb micro sd, is 72.99, and they provide free worldwide shipping.

 

wow, i bought my r4 at dealextreme.com (although i havent been keeping an update, im not sure if they still sell it) for 35USD with no 2gb micro-sd and 50USD with it. =\ maybe prices have changed?

 

why u people still looking at R4 or M3 ? they are out dated. these card dont support over 2GB memory. why not look at Supecard Ds one or cycloDS, they have features like Real Time Save and support upto 8GB.
