Invitrogene sells exactly this. The price is still shocking, considering
it is only a box with arrays of capacitors and resistances. Still,
about 2X cheaper than "regular" electroporators. Susprisingly, 
it works very well for all regular electoporation protocols for pro- 
and eukariots. For E.coli you will need 0.1 cm cuvettes as 
maximum voltage is 1.8 kV.
