The bots aren't that cheap, I agree. However...I made that money back in less than a week trading with it/them. I think you get 9 or 10 of them. The thing is though, I think you can use pretty much any bot that does what it says it is supposed to do...the lot size/TP ratio to account size is the major piece of this. What I would do if I were you...set up a demo account, find an EA that uses the martingale, is very simple, and runs off of one (maybe two) indicators only, run a handful of pairs and follow the lot size/TP schedule above. Watch the demo account for 2 months and see what it does. Demo settings:
Run 8 pairs - try these: GBP/CAD, GBP/JPY, GBP/AUD, EUR/JPY, EUR/NZD, AUD/JPY, AUD/CAD, USD/CAD
Set your lot sizes: .01 for first position, .03 for second position.
TP target: $0.50
Note, the draw down will follow the profit for a while. Eventually the profit will exceed the draw down. When you get the account to $4k, move your lot sizes to .02 and .06 with a TP of $1. Lather, rinse, repeat. After two months if you are making money in your demo account, set up a live account and do the same
There are a ton of free EAs out there. Grab one that makes sense and start demoing!
