what kind of riding do you do? this makes a big difference on what bindings you should look at.
for park: look at rome 390. everyone loves them and they are pretty cheap
for freeriding: rome targa and ride spi are both good choices. these may run over 200 dollars tho
as for flows, i dont really know much about them or their different models but from what i hear people either love them or hate them, it is really about preference. if they seem like something you would like, i would say go for it as long as you get one of the newer/ higher end models. the older/cheaper ones seem to have a lot of problems
