I am in the same situation with needing a vertical metal band saw. I first started looking at the portabands with a SWAG table. The problem with them is that they all have 0 throat capacity. Due to the offset design of the blade you only get 4 to 6 inches into a cut before your work runs into the body of the saw. Unless you are trimming out small pieces, they are not much use.
I have not found anything much beyond what others have shown here. There are the 4"x 6" convertible horizontal/vertical models. These range from $250 to $400
Grizzly
HF1
HF2
Rikon
And then there are the dedicated
upright Jet models which can cut wood and metal. These run $1500 to $2000 depending on the features
For those with more insight into this....are all the horizontal/vertical models probably made by the same manufacturer in Taiwan to each brands specification? I ask because they look nearly identical. If I decide on this style, is the Rikon brand worth $150 more over the Harbor Freight?
With the Jet 14 inch verticals, they have one model with 7 set metal speeds from 39 to 278 SFPM for metal and 3300 SFPM for wood, and another variable speed model with 90 to 340 SFPM variable for metal and 2600 SFPM for wood. This feature is about an $500 increase in price
If I choose to go this route, is the variable speed really worth anything or is it just another part of the saw that can break? And do you lose something by not being able to go below 90 SFPM? Three of the seven speeds on the standard model are slower than 90 SFPM.
