Well if you were looking at the spider II line,then I assume your in the $300-$500 dollar range.

The Spiders will give you some great metal tones for the money,but you might want something with a line out so you can hook up to a 4x12 cab if you want.

To me,the spiders seem like toy's.Not sure why.

Tube is definitley the way to go or even hybrid.Take a look into peavey or carvin for good bang for your buck.
