How much does rackspace cost? Any suggestions on colocation facities?

In 3-4 months, I'm going to need to rent space for a database server (dual processor with 1-2gB ramdisk, etc.). Low bandwidth requirements (20 kB up/down 24/7), but high uptime and good latency requirements (<50 ms).

How did you decide on where to host your stuff?
