Don't place too much creedence on what people say, it's a good idea to try out as many FX pedals as possible before spending any hard come by cash. Ask your friends what they have, maybe they'll let you try it out. Try it all out in the guitar store' yeah I know the store guys can be intimidating, and when they play they sound a thousand times better than you do, but ask yourself this, if they are so good, why are they still selling guitars. I have a zoom 505 which I've had for years, I never really used any of the pre-sets and am constantly changing the patches to suit my needs. I also have a Line 6 Flextone which is also very good. Don't rush into it, think carefully about what sound you want, it may be that a couple of stand alone pedals will do.
