Apex

We've
been using this highly-rated steel-reinforced car seat for awhile now (also have
a Recaro, a Britax, and a Sunshine Kids), and it's by far our favorite for the size,
versatility, comfort (um, for the pipsqueak, not for me), ease of use, ease of cleaning,
and storage.  This is by far the cheapest place to get it at $149.99 minus
10% off coupon (new customers use code: 10PERCENT unknown expiration date)
= $134.99 with FREE shipping!  It's a rather big seat though, so don't try
stuffing this in your Lotus Elise or Ariel Atom.
