I would take a look at your longer term goals.



If you're interested in Recruit a Friend, purely to level one or more additional accounts to higher level (or possibly several character combinations, on those accounts), but once you're there you'll basically never play more than one toon at a time...
Then a simple boxing solution might be better.

Hot Key Net is free, but it is script based.
Not sure how much scripting you would like to learn.
The basic script, which most people then adapt to their needs, might suffice.

The same is true for Auto Hot Key.
Although there aren't as many AHK users here, as there are HKN users.

Keyclone is a decent choice for keyboard broadcasting.
It isn't as powerful of a program, as some of the others.
If you want one character to do something, but not others... you need the others to have nothing on that keybinding.
Still, it gets the job done easily.
This is $20 once, and lasts forever (transferable to any future PC you upgrade to).

I'd recommend taking a look at IS Boxer.
Lax will give you a free trial, and the support level rocks.
This is a subscription level boxing option; but you can pick it up for a quarter (3 months), if the trial impresses you.



If you'll want to play multiple accounts, at maximum level...

It doesn't take that much more effort, to level 5 characters than it does to level 2 characters.
So maybe you decide on going 2, 3, 4, or 5.
Kill quests are the same, kill the mobs once and they all get credit.
Collection quests can be the same or progressively worse; many of these, everyone can loot their piece... but some force you to collect 'x' pieces on every toon.
The process of setting up a 2-box or a 5-box is essentially the same for time invested and complexity.

2-boxing is arguably the worst.
In that you suffer from lack of independent action -- you cannot have both of your characters doing two completely unrelated things at the same time (as two individual players could).
Meanwhile a 2-box doesn't have the firepower to outright kill something on a single nuke (x2), but that single nuke (x5) might take the target from 100% to 0%.

5-boxing is a full group.
If you include a Tank capable toon, and a different Healer capable toon, you have the option for Dungeon Finder, which is nice.

3-boxing is in between.
You might have the DPS to blow stuff up quickly... starting to gain more from the boxing advantage of focus fire than you're losing to the boxing disadvantage of lack of individual action.

Another consideration is time.
If you're lacking in time, and your schedule is kind of random... being your own group (or most of your own group) allows for self-reliance... you're ready as soon as you log on.
If the dungeon has six bosses, and after killing one of them has you saved to it, others will be pissed if you need to drop out; if you're the entire group, you can play as much or as little as you'd like and no one is going to be upset with you.
