I'm a bit late to the party here, but as I understood it Bethany's asking about parlours, not agencies. I don't think anybody here has a particular problem with a decent parlour because at least you're getting some tangible stuff for the lump of money you're handing over in terms of security, a place to work, a bit of company and so on. If you can't do incalls then I can easily see why somebody with a child would prefer to just turn up at work, work and then leave afterwards and if parlours were tolerated in my area that's almost certainly how I would have started off.
I think it's more that we have fewer parlour workers posting here for the reasons above - they don't really have any need to get involved with the online bit and are less likely to go looking for forums and websites than people planning to work by themselves and are therefore doing lots of research. As for working independently, it takes as much or as little time as you want it to really; it's certainly more time-consuming but you get to keep all your money, so what you really need to do is decide whether it's that or your free time which is more valuable to you. And don't forget there's nothing stopping you doing both, either
