Right, so you are looking for something in the $350 price range?
The Galaxy Nexus is a superb option if you're after the latest Android 4.2.1 though as you say it also lacks a Micro SD card slot.
Alternatively, the Galaxy S2 is still a viable option, especially if you are prepared to Root and install Android 4.2.1...
On the large end, the Galaxy Note (1st Gen) is still ok- not as fast as the N4 but hey, I'm currently using one on Android 4.1.2, with the intention of buying a N4 when it comes back in stock here in the UK, so it's surprising that you're looking away from the Nexus 4.
If you manage your space properly, you won't use more than 10GB.
