You could always get the Graco frame off of craigslist too, and possibly save quite a bit. I have the Snugrider frame, and I freaking love it! I bought mine as a set with a Graco Snugride 22 for $48 or something on clearance. I sold the car seat for $50, because I hated it. :)
That thing is worth every penny. My friend is currently borrowing it, and she uses it all the time. I think she said she has used her regular Graco stroller maybe 2x in the last 5 months.
