From the advice from above I looked at the Spider II and decided it had several features similar to the Cube. I read a lot of reviews and decided on the 112. 75W of power should be lots for what I need it for. Actually the Cube 30 probably would have been enough but I hate buying something only wishing shortly after I had spent a few more $$.
It should be here by the end of the week so I'll let you know my amateur impression of this thing.
