Re: *Spider II*
the roland cubes are great little amps.
and yes i would also check into maybe an older used tube combo, and even if you didn't like the distortion or if it even had distortion you could buy a nice pedal .
it really depends on what music your planning on playing as to what the best one is.
The vox valvetronics combos are a good vaule, espically if you have a nice overdrive pedal, i took my homemade overdriver to my local shop and plugged into one and it got realy good gain, i wasn't crazy about the vox's sound on it's own though.
for 389 you could get a fender ultimate chorus from ww-w.guitar^trader.-co-m (just take out all the little - and ^)
