I am using a Basic Stamp 2sx and want to receive nmea serial gps data
but I cannot find a way to receive and store the information, it is
sent at 4800 baud, 8 data bits, no parity. I think I might need to
get a different microcontroller.

Also, there's a GPS BS2 program and more information in the Files area
- just click the link on the left side of the page.

buffer and process the entire string from the receiver; using a BS2,
BS2e, or BS2sx is trickier as there is no way to buffer the day and your
SERIN commands become a bit complex. You may also need to do multiple
SERINs to capture all the data you require.
Here's a link to a customer project using a BS2 that you might find
helpful.

You an use a BS2 to receive NMEA messages at a maxim baud rate of
only 2400. You can commnicate with your GPS to change the baud rate
on the GPS. It works fine. The SX with its higher speed should work
ok at 4800. I can tell you for sure that the 2P24 works great @4800.
Use a Serin InputData list of variables or an array to store the
NMEA sentence as it comes out of the GPS and then "log" the data
into EEPROM using the Write command, or use the limited ScrachPad
Ram between sentences. Then do a wait for the next sentence.
