I hear you on the costs side of the equation.

I hope I'm not abusing forum etiquette by sending a link to a specific vendor, and Wayne feel free to blow this away if I am, but here is a like to the little amps. Note an optional power supply costs around $20 putting total cost around $50 an amp plus shipping and tax.

Looks interesting for sure without breaking the bank.
