Flojo - POF seems to have the worst of the bunch, although apparently there are some good people on there too. It's got more people than other sites, so it takes a thick skin and a lot of needle-finding to discover them though.
OKC may work better where you live - it takes time to answer the questions but I've found their 'Match percentage' is vaguely correct, compared to POF or Match.com
You can create a free profile on Match and some profiles are set up so you can contact them for free if you like them. You still get affluent spuds and affluent dicks who can afford it, but you won't get the teenagers at least - at least not with a full profile who can contact you.
People making comments about you are just morons with an anger issue. I'd discard their opinions, or if you want to, copy the link to 'psychotherapy' or possibly 'oedipal complex' from wikipedia and just send them the link to that in reply. That should shut them up.
