Dont buy a Tramontina, buy 10, Trams are by far my favorite.
I also have a highly modded 12" ontario which is very handy too.
I have had the most expirence with tram and ontario, been very happy with both.
Depending on the wood (hard, soft, green, etc) you should be more then fine with the trams. Give the 14" bolo a try, its a sick design :thumbup:
