I just used this with very good results: http://www.mouser.com/ds/2/405/sbos218a-125896.pdf

It has 254 steps I think, -95.5db to +31.5db, with .5db steps.

thanks! supposedly the one in the VTL doesn't have any op-amps in it and I was just curious to look at the datasheet and see how that could be.
