I was  wondering of anyone has built the amp shown at the link below.  It had 
my  interest for a while until it's power requirements were pointed out to me 
as  being a drawback, price-wise.

Check Motorola designs AN762 and EB63 on the given website.
 
Both of these are designed to run from 12 to 14V DC at maybe something like  
22A, so cannot understand the power supply problem. There are suitable power  
supplies available relatively cheaply for this in abundance. Believe the 
classic  design AN762 which is the basis of the linear amplifier in most HF 100W  
transmitters is featured in ARRL publications and is described in detail in the 
 RSGB Radio Communications handbook.
