Best Place for Blades?

I know this probably is one of those personal preference things but where is the best place to get sampler packs?



I've seen some posts about tryablade but just curious who else is out there?



Also, when I do find "my" blade, is there one good place to go to for blades or does it depend on what brand I go with?



Surprisingly the Dorcos haven't been bad but I think I would like something a little sharper.



Thanks for your input in advance!
