Absolutely go for the old style one! I have a safe n sound unity and it was the worst thing i bought! The old style are still the highest rated seat for under 6 months (the unity only scored 1 star!), they are also very lightweight in comparison to the new look capsules. I had a lecture from a physio about carrying the capsule around, they really are designed to be taken from the car and clipped into the pram, and shouldn't be carried around a lot. My shoulder still aches from carrying DS around in it and i haven't done it in several months now!
One downside is that the older style capsules can be used only up to 6 months, the newer capsules can be used for longer (mine is 12 months i think) so you would need to invest in a car seat sooner. But, you can hire the old style capsules very cheaply (i did this with DD and it was around $60 for the 6 months? might be a bit more as that was almost 4 years ago).
I have one of the old style capsules, without bub they are light as, but add 5kg they get pretty heavy! Easy enough to get in and out of the car as well. I hired mine for 6 months.
