I have been searching for a bike trailer/jogger for about 2 months now. When I get to a point that I decide on one, I find a new one that I don't know much about. So I am turning to this forum for help. I am needing this to tool around the neighborhood with my 2 kids, take it to the local amusement park, go jogging (although I am not an excellent runner). The items that are important to me are: can be a jogger/stroller (all kits included); easy transfer from trailer to jogger/stroller; folds compact enough to go into the trunk of a car; confortable seat (prefer sling), 5 point harness; prevents the trailer from tipping if the bike does, and of course price. The brands that I have been looking at are InStep, Croozer 535 (goes for around $350 - $400), Dreamer Design Exec Wide (found this on sportliquidators.com). Does anyone have any advise or information about these brands, especially the last 2 brands. I would like to get it very soon with the nice weather finally arriving. Thank you
