I have a Bob Revolution.

It is very pricy but so worth it! Trust me, I am a penny pincher and did not want to pay big bucks for a stroller. So, at first we opted for the Baby Trend Double Jogger. http://www.toysrus.com/product/index.jsp?productId=2796629
It was nice and had some great features. My favorite feature was that the canopy would tilt all the way forward to block the sun if it was facing the kids head on.It also had a great parent tray for keys and bottle of water,it also had a MP3 speaker so your kids (and you) can listen to music while you walk.
Let me clarify... I am not a jogger but really wanted a jogging stroller cause they manover soooooo much easier than the tandem strollers. Plus I wanted a side by side because whoever is in back of the tandem stroller can kick the seat in front and/or pull hair. Not that you would allow this behavior but even if it is the baby in back they don't know the difference and just do that stuff. Did I mention they are a bear to manover!
Okay, so after owning the Baby Trend for 2 months the front wheel began shaking and sticking so we returned it for a full refund! It was very kind of Babies R Us to do that!
Then we ended up purchasing the BOB because it got awesome reviews and it totally lives up to them other than the price. Too high for our budget but really does make life easier. The sun shades are sparated so if the little one needs it and the other one doesn't you can please everyone, You can purchase a parent tray that has two cup holders and a pouch for your keys, It has storage on the backs of both seats and underneath, I moves as smooth a butter! I am telling you I can move the thing with two fingers, hubby swears it rolls on it's own. It is so easy to move on pavement, dirt, stones or grass. The handle bars are nice and high so if you or hubby are tall you don't break your back slouching over to push it. The seats are comfy for the kids big and small. My 3 year old is the size of a 4 year old and he loves riding in it (especially when I go fast). It has a five point harness so they are in there secure. And the shocks on this thing are awesome. The kids can bounce in it as if they were in a boucy house!
We get compliments on ours all the time!
YOu are looking at the right time of year. Take your time and do your homework. I did the same last year and spent my winter selling stuff (from around the house) on ebay to raise the money for the double stroller. It cost us about $400! I figure I could use it for a few years and resell it for a good price too. YOu might notice more and more of them around.
If you wanted to do a similar stroller to the Baby Trend, we also looking into the Schwinn Double Jogger. It was good and had some nice features, again the sun visor when all the way forward and the price was reasonable. They are hard to find in stores to try them out too.
We got our Bob for $100 off at happymothers.com
they were great!
My recommendation is to try it before you buy it. Sit the kids in it and push it around.
Let me know if you have any more questions.
