I really like perfect hunter from rsbotting. It has an automatic start button, all you need is starting items in inventory and it does everything else for you ^^, also decent cash at chinchompas.
WC'ing - Crap, unless you want to cushion your account with some serious exp don't buy it. I got about 50M WC'ing exp and no ban. The nest's come to be about 60k/hour @ Ivy with a rabbits foot.
Slayer - Decent but hard to setup, slow and I personally don't trust it. Buy if you want 85 slayer for abbys.
Hunter - Biggest piece of crap I've bought. High ban rate and is a terrible 99.
Summon - Amazing bot, barely any set backs and is cheap aswell. You make about 400k/hour pouch to scrolling heavily bought scrolls. http://runescape.wikia.com/wiki/Calculators/Scrolls/High now times the number by 2k-2.5k and that is how much you will be making before kyatt pouches and RoD's. I also like it for it's high speed and simply because summoning is so boring to train and such good xp/hour.
