25% argon will give you less spatter than 100% co2. It costs a little more. Nice especially on thin metal or tubing. Less cleanup on peices you want to look really nice.
Generally metal blades are for saws specifically made for metal blades. They turn slower than most abrasive saws. But others may have some other experience in that area. Generally for the hobby or small shop user the abrasive blades are more than adequate. Eye protection on any a must.
If you want a metal blade in addition to an abrasive chop saw, I would recomend one of the hand metal saws. They look like a Skillsaw wood saw but turn slower and have a metal shield and blade made for metal. They used to be horribly expensive but some decent saws are now available for the budget of more occasional users. They are handy on projects where the metal can't come to the chop saw.
