Infant Car Seats

I am on the hunt for an infant car seat. Not only am I looking for a great deal but I want to find that great deal with exactly the specifications I want. I thought I found the travel system that was perfect until I talked to my sister-in-law last night. She said she loved the stroller but didn't care for the infant seat. There is no way to strap it into the car without a base. Very inconvenient if anyone else is to pick baby up. I guess this means I will be looking for a new travel system.
