I just priced up all the parts for a 5E3 and if I was to get almost everything from Evatco it comes in just under $800 for everything except the cabinet which I'd make myself. Shopping around may save a few $$ here or there and making the Chassis would also save some $$.
Just in case anyone else is following this thread and is interested, here is a rough breakdown not including a cabinet:
Speaker - $127.95
Power Transformer - $169
Output Transformer - $89
Chassis - $80
Tubes - $139.40
(2 x 6V6 Power Tube - $68
5Y3 Rectifier Tube - $29.95
12AX7 Preamp Tube - $18.50
12AY7 Preamp Tube - $22.95)
Resistors - $2.65
Caps - $65.56
Everything else - $126.97
